5 Primary Challenges and Arrangements to Enlisting and Overseeing Farther Engineers

Programmers Brain PVT LTD .

Did you know that 51% of workers convey superior comes about whereas working from domestic much appreciated to less diversions and distant better;a much better;a higher;a stronger;an improved work environment? What’s more, 85% of directors claim that proficient inaccessible groups will ended up the unused reality within the up and coming a long time.

In spite of the fact that your group of farther engineers won’t be in plain locate, it doesn’t cruel they will In spite of the fact that your group of farther engineers won’t be in plain locate, it doesn’t cruel they will get loose and diverted from the consolation of their claim homes and won’t provide the comes about you require. Working with a group of prepared inaccessible computer program engineers, you’ll coordinate with tech abilities from around the world, get superior comes about, remain ahead of the competition with inventive arrangements, and cut down costs.

Whereas overseeing a inaccessible group has its challenges, the result is worth it! To assist you avoid a few of the foremost common botches and guarantee your group of farther designers is beneficial and engaged, we’ve come up with solid arrangements to defeat these challenges for great.

Hiring Remote Developers: Main Challenges and Solutions 
Communication Issues

Such a long period of as it were seeing each other through Zoom gatherings and chatting in flag-bearers has influenced the way inaccessible computer program engineers collaborate and communicate. Whereas within the office individuals can’t maintain a strategic distance from talking to each other and coming up with arrangements together, a virtual environment might make group individuals less comfortable to inquire questions, recommend their claim thoughts, and take an interest in discourses from distinctive areas.

Working with engineers around the world, you’ll be able moreover confront the dialect obstruction issue as the lion’s share of your group individuals aren’t local English speakers. Such an issue might lead to dissatisfaction and various mistaken assumptions from both sides, slowly diminishing the efficiency level.


Coming up with an efficient and responsive set of communication channels will solve this problem before it occurs. For instance, you can choose Slack for instant messaging, Google Drive for document collaboration, Zoom for video conferencing, and InVision for prototyping. 

With such a set of communication channels, you won’t have to be rummage through a bunch of mail discussions and flag-bearers to induce the info you require. Attempt to restrain this set to three or four computer program choices so simply can continuously know what to anticipate from a specific communication channel.

To fathom the dialect obstruction issue, all you’ve got to do is contract a solid extend supervisor for your group. They will offer assistance with all issues you might confront and avoid you from future issues.

Following and Overseeing Your Team’s Efficiency

Whether you need to contract a group of inaccessible designers or fair discover a few farther computer program engineers to reinforce your in-house staff, overseeing a venture may gotten to be challenging when your representatives are spread out over the nation or indeed the world. In the event that you’ve got a complex venture or your group of engineers is expansive, it may be troublesome to oversee your team’s efficiency and keep track of person assignments.

Designers perform handfuls of person errands on a every day premise, so it’s moreover basic to form beyond any doubt merely can keep track of advance towards your objectives and stay up to date with any changes. Collaborating with inaccessible engineers, you’ll be able moreover feel a need of criticism from a group that can lead to errors and clashes.


On the off chance that you need to organize a farther group and keep designers as beneficial as conceivable, you’ll be able dole out this challenging errand to a devoted extend director and center on more vital errands to develop your trade. On the off chance that this strategy doesn’t work for you, a wide run of extend administration devices will come in helpful to improve your team’s efficiency.

Trello could be a incredible instrument to preserve the way your workers perform, organize all sorts of errands, and use a time tracker to boost your team’s execution. Utilizing Trello, you’ll be able set up customizable workflows, make dashboards, and coordinated such instruments as Slack, Intersection, and Google Drive. Your farther group will be able to collaborate there, share records, and take off comments to remain beneficial and organized.

In case you’re searching for an easy-to-use and customizable administration apparatus, Airtable will meet your prerequisites. Other than dashboards and a time tracker, it’s moreover conceivable to automate such work forms as ask endorsements and tech stack to assist your group provide superior comes about. Coordinated Airtable with any apparatuses, from GitHub and Evernote to Google Calendar and Dropbox, and move information back and forward at whatever point you would like it.

You’ll be able too plan every day check-ins to urge standard input from your group and remain associated. Inquire your workers around today’s assignments, make beyond any doubt they don’t have any specialized issues, and discover out in case your inaccessible engineers fulfilled their past errands.

Time Zone Distinction

Inaccessible working has given us a incredible opportunity to contract farther representatives around the world and come up with cutting-edge arrangements for any industry. But it too implies time zone contrasts, so you’ll be confronting an critical issue in your venture at 9 AM in Unused York whereas your remote engineer is getting to bed at 11 PM in Sydney. As a result, you’ve got to hold up for hours to talk to your representative, putting a extend and a level of efficiency at chance.


You’ll be able beat this challenge with a set of rules for your farther group and make a plan to fit your employees’ time zones and keep your project on track. In this way, you’ll be able get it who and when is progressing to be accessible on a every day premise. Attempt to organize gatherings and every day check-ins when center group individuals are working.

Utilize Teamup Calendar to organize your work, make plans, oversee your developers’ accessibility and nonappearance, and share occasions along with your group. You’ll be able moreover supplant time-consuming check-ins with Status Hero and let your designers type in brief day by day reports. Utilizing this apparatus, you’ll too collect movement from such instruments as Trello and GitHub, make custom reports, and track your team’s advance.

Trust Issues

Working with inaccessible engineers, you’ll confront a common issue of believe issues among laborers. In-house team members have a long time to urge to know each other and construct believe within the work environment, whereas your workers have never seen each other in genuine life. In the event that one of your group individuals gets stuck and can’t inquire anybody for offer assistance, they will lose a part of valuable time and costs battling to total this assignment on their possess.

To convey top-notch comes about and perform superior, you’ve got to know approximately any concerns your engineers may have at work and help them deal with these issues. Be beyond any doubt that it’s pivotal that each part of your farther group feels esteemed by their colleagues.


Keep in mind that believe among your farther representatives begins with you! It’s imperative to let engineers know you’re prepared to deliver them enough opportunity to create their own choices and botches, but remind them you’re continuously here to step in on the off chance that essential.

It doesn’t cruel you’ve got to disregard around your group and let them bargain with everything without your control, just attempt to dodge micromanagement because it annihilates your group. Rather than keeping track of each modest detail, it’s superior to set up the venture objectives and record your workflow for way better optimization. Don’t disregard to characterize which assignments are crucial for you to be included in and let your group individuals handle less vital assignments on their possess. It’s all approximately adjust and we are beyond any doubt you may discover it!

Unplugging After Work

It’s really a colossal issue as 18% of farther representatives can’t switch off from work and keep up a sound work-life adjust. The tall level of adaptability has made it more challenging for specialists to urge a break and elude unending records of assignments to total. This genuine issue can lead to burnout and anticipate your group individuals from remaining centered and keeping a adequate efficiency level.


The most perfect way to assist your farther group unplug after work is to set reasonable day by day objectives and due dates. Overburdened with a gigantic sum of critical assignments to perform, inaccessible engineers will get baffled, begin working after-hours, and reach the point of burnout some time recently completing your extend.

Remaining on a plan is one more way to keep your group locked in, spurred, and adjusted. Inquire your representatives to create their availability hours known to everybody within the team and don’t irritate them after working hours. You’ll too recommend your group individuals utilize apps like Daywise to plan notices and appreciate their free time without going crazy from advanced over-burden. Your workers can moreover utilize these apps at work to decrease diversions from their smartphones and be more beneficial.

Make Your Challenges Work For You 

Enlisting inaccessible designers, it’s fundamental to be beyond any doubt the most challenges you might confront whereas managing your group and the leading ways to overcome them. From communication and administration issues to a lack of believe and time zone differences, LITSLINK is continuously prepared to defeat these challenges and guarantee you’ll collaborate with experienced farther designers to realize your trade objectives.


How Can You Effectively Calculate Computer program Advancement Costs in 2021?

Programmers Brain PVT LTD .

Building computer program to address your commerce needs could be a must in this advanced age, not an in the event that. As such, it regularly comes down to the advancement taken a toll and proficiency. The speedier you make groundbreaking arrangements, the speedier you overcome competition and set up yourself as a driving player. Understanding fetched estimation standards is the key to victory. With costs to create progressed computer program shifting significantly, many factors to consider to discover the most excellent approach conceivable to save your budget.

You’ll rapidly run the taken a toll of building your computer program utilizing our taken a toll calculator or examined the article in profundity to pick up distant better;a much better;a higher;a stronger;an improved”>a stronger understanding of what lies at the center of the estimation.

Approaches To Cost Estimation

In case you’re just getting started along with your exceptionally to begin with extend, you will discover it challenging to estimate the taken a toll of program advancement. Fortunately, there are a few ways to calculate the ultimate cost tag of your custom program advancement.

One choice is to utilize the bottom-up assessing strategy. This strategy rotates around partitioning the extend into stages and assessing their costs independently some time recently inferring the ultimate cost.

The practically equivalent to evaluating strategy depends on values inferred from comparable ventures and can grant you moderately precise expectations in the event that the distinction between the two items is inconsequential.

On the other hand, you’ll depend on master judgment to decide program advancement estimating. Master evaluation is based on the information from past ventures, advertise environment, and idiosyncrasies of chosen innovations.

Normal Rates On The Advertise

Separated from investigating taken a toll estimation strategies, you’ll be able continuously check the rates for custom program advancement on the showcase. Let’s expect you need to construct a moderately  basic versatile application to back your commerce.

In this case, you’ll be able anticipate a advertise normal rate extending from as moo as $25 to as tall as $149 per hour. The cost for custom software and web improvement will drop within the same extend, allow or take.

The contrast in rates is based on the estimate and expertise set of the group. Additionally, the cost may change depending on the special highlights of your extend, its complexity, and the outsourcing locale. Underneath we are going break down these contributing components in detail to get it their significance to come up with exact taken a toll gauges.

Factors Affecting Software Development Costs

Custom computer program improvement includes numerous stages ― from a revelation assembly to the venture dispatch, there are parts of variables to consider. Knowing how these components compare with venture necessities will offer assistance essentially with taken a toll estimation.

Number of Features

The usefulness of your application or administrations is one of the basic components influencing the taken a toll. Applications with less highlights can be created quicker and cheaper compared to those with expanded usefulness. A wealthy highlight set in intellect for your extend will require more abilities and involvement from your improvement group. Unnecessary to say that UI/UX plan is additionally subordinate on the number of highlights your program will include.

Also, the more highlights you arrange to actualize, the more testing will be required to guarantee the solidness and security of the item.

Tech Stack

Custom computer program advancement includes both frontend and backend to construct a versatile and feasible item. Depending on the complexity of your future program, the scope and scale of the stack included will shift incredibly. Thus, evaluating computer program improvement costs is specifically tied to the advances you employ to construct your item.

Frontend Technologies

Frequently called client-side, frontend alludes to all things related to the users’ interface. Web applications, for illustration, will have the taking after components in their frontend stack: CSS, HTML, and JavaScript.

Backend Technologies

This perspective of program improvement includes all things related to databases, APIs, and servers.

Since each program extend is special, you’ll not discover a one-size-fits-all arrangement when choosing the tech stack. Nevertheless, several variables will assist you distinguish the leading tech stack whereas evaluating the fetched:

  • Adaptability. In case you’re arranging to construct a scalable application, you will conclusion up with a complex stack to be required for the extend.
  • Time to advertise. On the off chance that you need to require your item to the showcase ASAP, consider choosing well-tested or progressed arrangements.
  • Improvement and Support Costs. Since assessing computer program advancement costs is front and center, you ought to consider arrangements and systems that will not deplete your budget.

Staff Experience

The fetched of program improvement is additionally specifically tied to the involvement of program engineers working on the venture. Based on their aptitudes and information, engineers can be junior, center, and senior.

  • Junior designers are as a rule at the starting of their careers and depend on the back and direction of experienced colleagues. Here at LITSLINK, we moreover have a board of profoundly gifted program designers who direct ventures, coach junior masters and guarantee their opportune and uncompromised completion. We too run knowledge-sharing workshops on a customary premise to bring our junior designers up to speed quicker.
  • Center engineers are more independent and built up pros who may command a few systems or programming dialects and seldom require direction.
  • Senior engineers can contribute the foremost to your venture due to their noteworthy involvement. These masters can offer inventive and all-encompassing arrangements to adapt up your extend rapidly.

Actually, the taken a toll of your extend will go up when working with center and senior engineers. In any case, experienced designers offer important skill and industry information to your ventures.

Project Complexity

One of the foremost significant subtleties that contribute to program advancement fetched is venture complexity or project size. In the event that you elect the T&M approach, the more complex the extend is, the more hours it’ll require to total, and as a result — the more costs will be went through. In computer program advancement, able to partition complexity into three levels:

  • Easy: Those are moderately little ventures that ordinarily require changes or updates to existing computer program. Such ventures take comparatively small time to total and a littler improvement group to see it through.
  • Medium. These ventures tend to be more work-intensive and require engineers with more progressed aptitudes to see it done. Still, these ventures are attainable and convey unmistakable comes about.
  • Complex. As the title suggests, these ventures display a specific challenge for the improvement group. Complex ventures frequently include the integration of different frameworks, security, databases, and components. Multi-platform arrangements and modern commerce frameworks are among such ventures.

As pointed over, complexity is an clear contributing figure to consider when evaluating the advancement fetched of your computer program.

Team Composition

Numerous tend to neglect the composition of the improvement group as less important when making a program advancement fetched estimation. In spite of the fact that less self-evident, this figure is among those that influence the ultimate result and venture budget. Regardless the aptitudes, group composition can be clarified utilizing three non specific sorts.


In improvement, generalists specialize in numerous ranges rather than centering on one region of obligation. Such groups are as a rule constrained in measure and can handle one venture at a time. Choosing a generalist group is an ideal choice for ventures of little complexity.


This sort of a improvement group can unravel complex ventures that require a nuanced understanding of industry-specific subtle elements. Tech pros can work ponders with complex ventures and optimize the program improvement cycle.


Expansive ventures require committed groups of both generalists and masters to total in time. You ought to choose such groups when quality is of the pith and incite advertise rollout is verifiable.


Outsourcing program advancement is frequently the foremost sensible and cost-effective way to construct a item, particularly at the early arrange of a extend., There are a number of well-established outsourcing districts out there. Each of them has its stars and cons you ought to carefully consider some time recently choosing a advancement partner.

East Europe

This IT locale is quickly picking up force as one of the foremost productive and beneficial universally. With flooding tech talent, Eastern Europe could be a promising outsourcing goal.


  • Skilled Specialists
  • Reliable Workflow
  • Good Cost Effectiveness


  • Remote Communication


As an IT locale, India is by distant the biggest and most dynamic one. In any case, there are numerous complaints with respect to the conflicting quality of improvement administrations.


  • Extensive Talent Pool 
  • Budget-Friendly
  • Established Momentum


  • Low Quality
  • Communication issues 

West Europe

Verifiably, West Europe built up itself as a dependable IT locale with a runrangeextendrun of devoted companies and talented engineers.


  • Great Talent Pool
  • Stable Productivity
  • No Language Barrier


  • Higher Rates 

South America 

In later a long time, South America sloped up its IT segment, getting to be a capable nearshore choice to a few companies considering outsourcing their ventures.


  • Decent English
  • Growing Talent Pool
  • Considerable Performance


  • Higher Rates 
  • Cultural Differences
  • Lack of High-Skilled Specialists

As you’ll see, the choice of the locale to outsource your ventures can be a complicated one since you’ve got to account for all the conceivable benefits and downsides.

Final Thoughts

With numerous components contributing to the ultimate cost tag and challenging choices to form along the street, you would like to consider everything previously from the choice of an outsourcing locale to the group composition and tech stack

You guarantee smooth participation and straightforward communication along with your formative accomplice after you know how the taken a toll is evaluated.


React and React Native: What’s the Difference?

Programmers Brain PVT LTD .

React vs React Native are the innovations that have been demonstrated to be compelling in creating adaptable web and versatile arrangements. Both of them were created by Facebook to quicken the creation of web and portable client interfacing utilizing one of the foremost broadly utilized programming dialects – JavaScript.

React is an open-source JavaScript library for building client interfacing. It was made by Jordan Walke, a computer program design at Facebook. There was an objective of rapidly building adaptable interfacing, and React.js came into presence to disentangle JavaScript improvement. Taking after the victory of React.js, Facebook looked to provide all of its benefits to portable and created Respond Local – a system for making cross-platform portable apps on iOS, Android, Windows, and other stages.

React and React Native is behind a few of the foremost well-known web and portable applications. They speak to diverse viewpoints of the React environment and serve diverse purposes. So, let’s take a jump profound to get it when it’s superior to take React.js vs React Native

Presentation to React.js and Its Highlights

What is React.js?

React (aka React.js or ReactJS) could be a JavaScript library for building responsive client interfacing. It was open-sourced at JSConf US in May 2013. Agreeing to Google Patterns, React has been gathering steam since 2017, and it appears no signs of halting. React is broadly utilized in web improvement to construct comprehensive apps and computer programs.

The library is based on JavaScript, which implies designers can get to a distinctive society of donors who have made a massive environment of instruments to create an engineer’s lifeless demanding, including React Designer Devices (assessment of the progressions of components within the vDOM), React Locate (visualization of component pecking order tree). You’ll be able to remain upgraded on the patterns through React’s official channels.

Striking Highlights of React.js

React may be a well-known choice for web ventures due to its gentle learning bend, moderately quick advancement, and striking execution, which permits building web applications of different scope and complexity.

  • Optimized Execution

Virtual DOM is one of the characterizing highlights of React. It ensures the least overhaul time to the genuine DOM, gives higher execution and distant better; a much better; a higher; a stronger; an improved”>a stronger client encounter.

  • Helpful Investigating

The component-based design in React dispenses with the requirement for visit investigating. On the off chance that you alter one portion of the app, it doesn’t influence other parts.

  • Tremendous Community

Being one of the primary JavaScript libraries, React.js has accumulated very a swarm of adherents. It appreciates the back of both Facebook and is favored to have a colossal community of computer program designers that gives important arrangements that encourage the improvement of the innovation.

Sorts of Ventures React.js is Best Suited For

What is React’s most far-reaching utilization? Its reason is to permit building high-performing interfacing. React plays an imperative part in:


To begin with, utilized for the newsfeed, React is utilized broadly for the net adaptation of


React was actualized to roll out the net adaptation of Instagram. API demands with Google Maps, geolocation administrations, look usefulness, and labeling is bolstered through the system.


Asana, a driving venture administration instrument, utilized React to address client-side execution issues. The front-end was revised in React.


As composed on the Netflix web journal, React empowered them to construct a colossal establishment. React was received since of its startup speed, runtime execution, and measured quality.

Encourage away from home, Airbnb, WhatsApp, Dropbox, Yahoo Mail, Medium, Udemy, Codecademy, and Unused York Times all utilize React.

How does React.js Differ from Its Rivals?

Nowadays, Facebook’s innovation appreciates gigantic rates of developing ubiquity. React is the foremost broadly utilized JS library – it has gotten to be a go-to choice for most front-end engineers.

  • The groundbreaking highlight of React is Virtual DOM. It doesn’t require a reaction from a browser, which is why the code is rendered speedier. Virtual DOM gives higher execution, and distant better;a much better;a higher;a stronger;an improved”>a higher client involvement compared to physically taking care of DOM changes.
  • Another conspicuous include is the capacity to reuse components – engineers don’t ought to type in distinctive codes for comparative app components. React presented the concept of component-based engineering, which upholds the reusability of components as per your prerequisite. It can spare an colossal sum of time.
  • Since React is competent of server-side rendering, it gives a control boost to SEO (with the utilize of additional devices like Next.js, for case).
  • Community-powered development makes React one of the foremost prevalent alternatives for making imaginative apps.

Introduction to React Native and Its Features

What is React Native?

React Native empowers building native-like versatile apps for Android, iOS, and All-inclusive Windows Stage (UWP) and other stages. In 2012 Check Zuckerberg commented, “The greatest botch we made as a company was wagering as well much on HTML as restricted to native.” He guaranteed that Facebook would provide distant better; a much better; a higher; a stronger; an improved”>a stronger versatile involvement. React Local was created after React to meet the developing requirements in high-quality cross-platform improvement. It was open-sourced in Walk 2015.

Sometimes recently React Native was concocted, designers had to utilize different devices for diverse stages. React Native permits, versatile app engineers, to spare a parcel of time – your group won’t scatter endeavors on making one app for iOS, one for Android, one for Windows, etc. Most of the JS code may be reused and improved with local modules or code.

Agreeing to the Stack Flood overview 2020, React Native is one of the foremost well-known innovations – 58% of the respondents said they utilized React Native for portable app improvement.

Eminent Highlights of React Native

React Native acquired most of the benefits from its senior brother. But in differentiate to React.js, React Native is utilized for creating versatile apps that can be run on a few stages. In expansion to that, it has platform-specific APIs, plan designs, and other contrasts. React Native has demonstrated its capability to offer an environment where you’ll be able to effectively to construct your versatile apps.

Code Reusability

The sparkling accomplishment of React Native is that engineers don’t ought to compose isolated codes for iOS and Android platforms. Also, they can in part share the code for the net, which permits for way better cooperation.

Reduced Costs

As there’s as it were one code base for all stages, React Native can be utilized to construct applications that are consistent with Android and iOS. This implies that the group will spare on the advancement, upkeep, and regulatory costs. The other cost-saving comes from the truth that React Native is totally license-free.

Responsive UI

React Native is competent in giving clients native-like encounters because it utilizes local UI in creating responsible mobile apps. In case you’re on a budget but require a cost-effective and quality arrangement that would run on a few stages, React Native is your choice.

Hot & Live Reloading

In case the trade rationale has to be altered, you’ll be able to change the client interface without any misfortune of your app’s code.

Declarative UI

The thought behind this include is beautiful basic — it renders substance by returning a few JSX. Versatile UI is based on an explanatory programming worldview – engineers can center on what is required to be actualized instead of how to do this.

Rich Community

React Native was conceived through a Facebook run hackathon, and since that point, it has been broadly bolstered by its community. In the event that you confront any issue amid the improvement prepare, it’ll be effectively fathomed. An expansive worldwide engineer community persistently contributes with their information, arrangements, devices, etc.

How Does React Native Differ From Its Rivals?

On the off chance that you would like to construct an app that you just can effectively dispatch on a few stages, there’s nothing way better than React Native. Nowadays, it is an undisputed pioneer within the specialty. These aces grant React Native the edge over other cross-platform systems:

  • One of the major focal points of React Native is that it lets you create native-like apps but doesn’t compromise on client encounter or code quality.
  • React Native lets you essentially cut your product’s time to showcase. Rather than building two separate apps, you’ll be able construct one code base and dispatch it, which decreases the improvement time.
  • It employments JavaScript, which makes move from web to portable advancement less demanding. What does it cruel for you? Finding React Native engineers is regularly simpler, which moreover contributes to speedier portable improvement.
  • Not at all like Cordova, PhoneGap, and other cross-platform systems that render code by means of WebView, React Native renders certain code components with local API’s.
  • The component-based structure permits engineers to construct apps with a more spry approach than most cross breed systems.
  • React Native gives a module that recognizes the stage in which the app is running and loads the proper code for the proper stage.

Sorts of Ventures React Native is Best Suited For

React Native is fueling a few of the foremost well known versatile apps, counting:

Facebook’s Mobile Applications

Most app and Facebook Advertisements are built on React Native for Android.

Instagram App

After Facebook procured Instagram, React Native was coordinates into Instagram’s local app.


In 2017, Skype declared that the app will be totally revamped in React Native. It was utilized not as it were for the portable stages but moreover on the Windows desktop app.


Tesla employments React Native for apps that bolster their Powerwall battery and savvy car items.


The versatile application of WIX, a celebrated site builder, is totally composed in React Native. Tal Kol, previous head of versatile building at Wix, said that React Native was a game-changing innovation for Wix.

React and React Native Highlights

The distinction between React and React Native is noteworthy. React is outlined for web advancement while React Native is utilized for cross-platform versatile advancement. Let’s whole up a contrast between React and React Native in a brief checklist. Underneath is a diagram of both – it ought to donate you a reasonable thought of what makes them distinctive to form an educated choice based on your needs and anticipated result.

Outline of the Portable Advertise

There’s no denying that the utilization of versatile phones is winning the race within the tech world. Agreeing to Statcounter, in 2019, the number of those who utilize versatile gadgets is altogether higher that of desktop and tablet clients:

  • Mobile — 53.29%
  • Desktop — 43.99%
  • Tablet — 2.72%

This information implies that having an online site tailored to fit the desktop screen isn’t sufficient any longer as everybody is attempting to make their way into the humongous universes of cutting edge “palm computers.” And indeed if you’re dead beyond any doubt that your app will make a sprinkle, you still have to be weigh up a parcel of essential factors. Have you chosen which stage to select? Gratefully, this can be not that troublesome. To assist you reply this address, you’ll be able address Statcounter once once more.

This truthful information is aiming to shed light on the foremost well known portable working frameworks all through the world, and more particularly, within the US, Canada, and Europe.

As you’ll clearly see, the undisputed pioneers are Android and iOS. So, why stand up to the allurement to combine the benefits of both universes?

But whereas replying the stage address is generally simple with all the measurable information you have got at your fingertips, it’s still bothersome to choose up the correct sort of portable improvement. So presently we’ve at long last come to the center of the article — is it way better to utilize an app or the site application?

Diagram of the Most Sorts of Versatile Improvement

To form your product or administrations mobile-friendly, you’ll be able consider three fundamental sorts of advancement approaches. In this way, you’ll construct local apps, versatile site apps, or crossover applications.

But some time recently considering the masters and cons of each approach, let’s see what the distinction between a versatile app and a portable site is.

The portable app may be a program program that you simply download from an app store or commercial center onto your smartphone. Versatile apps can be local, which suggests that an application is made particularly to run on a specific portable working framework, like iOS, Android, Windows, or any other. There are moreover half breed apps, which can have a single codebase and run on distinctive stages.

A web app, for its portion, is an application simply don’t ought to download on your versatile gadget but merely can effortlessly get to in a browser on your smartphone.

Presently, you’ll have a closer see at a versatile app vs web app and their aces and cons.

Native Mobile Applications

As expressed over, a versatile local app is built particularly for a particular stage, let it be iOS, Android, or any other os out there and with the assistance of “native” dialects. For instance, for iOS you’ll utilize Objective-C, Quick, and for Android apps — Java.

This sort of portable advancement is very common and it has its major preferences as well as impediments.

Pros of native mobile apps:

  • You’ll get to and effectively utilize all the native features of a portable gadget, just like the camera, GPS route, accelerometer, swipe route, thrust notices.
  • Local versatile apps can work offline, which can be significant for a part of businesses, like portable gaming new businesses.
  • Much appreciated to the reality that such applications are built for a particular stage, it makes them surprisingly quick and proficient.
  • As a run the show, local portable apps are instinctive and intelligently.
  • New businesses are able to include them to different marketplaces and app stores to disseminate them among clients.

Cons of local versatile apps:

  • “Native” programming dialects are harder to utilize than those for portable web.
  • Be prepared to spend a buck on building a local application as it’s made to suit a particular OS. On the off chance that you want to have a local app for iOS and Android, you’ll ought to pay very a whole for both of them as they’ll be created as standalone applications.
  • Such local portable applications are harder to preserve.
  • In general, to make a local versatile app can be awkward and expensive for new businesses.

Mobile Web Applications

Not at all like versatile apps, you don’t got to download them onto your gadget. Your versatile web browser, like Chrome, Safari, Firefox, or Musical drama, would be flawlessly sufficient to utilize your administrations or item.

Stars of portable web applications:

  • One of the most points of interest of portable web apps is that it’s a cost-effective way of improvement. You are doing not ought to pay for standalone apps to run on specific stages just like the case is with the local improvement.
  • Simple to have and keep up.
  • Simple to construct and no impediment within the choice of a dialect. It incorporates a moo learning bend. To construct a web app, you would like to have information of JavaScript, HTML & CSS.
  • Reasonable for any stage, that’s why you’ll effectively envelop the total portable advertise.
  • Your web app will run on numerous versatile gadgets inside a browser.
  • Such web apps are superbly consistent with other gadgets like a portable workstation, for illustration.

Cons of portable web applications:

  • To get to a web app, you must have an online association. Something else, you’ll disregard approximately utilizing it.
  • No desktop symbol on the screen of your versatile gadget.
  • As well numerous activities to get to an app. You have got to open your browser, sort a required URL, etc.
  • They are less instinctive and give immaculate client encounter.
  • No get to to local highlights like GPS, camera, thrust notices, etc., which makes it an totally far-fetched choice for new companies.
  • Versatile web apps are much slower than local portable applications.

Cross breed Applications

Cross breed applications speak to an appealing cross-platform advancement alternative, which combines both local versatile app vs versatile web advancement approaches. A half breed app works in a holder through a system. Here are the most points of interest and drawbacks of such applications.

Masters of half breed applications:

  • This sort of advancement is cheaper than the local one as you’ll run a single codebase for all stages.
  • You are doing not have to be have a browser to run a half breed app.
  • It’s nearly outlandish for an normal client to recognize between local versatile applications and half breed ones.
  • One codebase is simple to preserve.
  • You’ll have simple get to to all the local highlights of a portable gadget.
  • There are a part of cross-platform systems to select from to make a versatile app: Respond Local, Shudder, Ionic, etc.
  • Cross-development is speedier compared to other alternatives.

Cons of half breed applications:

  • Whereas it’s cheaper in comparison with the local versatile app improvement, it’s still more expensive than the portable web advancement.
  • Slower than local apps.
  • A bit less intelligently

Outline of Mobile-optimized Site vs Responsive Web

In case you still chosen to go with the portable web, here are a few choices of such improvement, you might need to see at — mobile-optimized websites and responsive websites.

Responsive Site vs Versatile App.

Responsive plan may be a uncommon sort of plan that can be custom fitted to be utilized on distinctive gadgets — a portable workstation, versatile phone or tablet. It implies that your site can adjust to different contraptions notwithstanding of the measure of their screens. In this case, the “one measure fits all” is the coordinate representation of it. Responsive site “responds” in like manner to the screen of a gadget and renders substance.

This approach contains a strong advantage over the other ones: it is much cheaper than local or cross-platform improvement.

Portable Optimized Site vs App.

On the opposite, mobile-optimized websites are made to suit portable browsers. Substance and plan are optimized to form a more user-friendly encounter to utilize the site vertically.

The negative angle of a mobile-optimized site is simply need to construct a portable form independently from the net one.

Wrapping Up

What you moreover have to be be beyond any doubt is the reason of your startup. For occasion, on the off chance that you need to have an Uber-like app, diversions, or any applications that require to have get to to local highlights of a versatile phone, the choice for you is crossover or local portable improvement. But in the event that your startup needs your site to be compatible with portable and user-friendly for your client, you’ll consider the portable web, as a responsive or mobile-optimized site. Be beyond any doubt to check out our versatile program improvement case thinks about to see what approach may be the finest for you.

Still, to guarantee the best quality client encounter and on the off chance that you’ve got essential assets, you’ll be able continuously go for portable applications and websites without comparing versatile web vs versatile app.


How to Successfully Scale Your WebRTC Application in 2021

“How do I scale this?”

This is a question that is asked eventually, often too late but never too early, by everyone that builds successful web-based software products.

The importance of a plan for scalability is hard to overstate, but unfortunately, it’s often left until the last moment when something has already started to fail. It’s even more important for applications that incorporate Web Real-Time Communication, or any other real-time communications technology, especially if video is an integral component.

So how do we scale WebRTC-based applications?  Thankfully, it’s not that hard. You just need the right pieces in place.

webRTC scaling

How to Scale WebRTC Applications

To get started, take a step back and look at how your application uses Web Real-Time Communication. Ask yourself these questions:

  • What is the maximum number of users I need to support in a session?
  • What is the average number of users I expect to support in a session?
  • How many users will send media within a session?
  • How many users will receive media within a session?
  • Will my users typically connect from residential or corporate networks?
  • Will my users connect in from high-security networks (e.g. hospitals)?
  • What do I need to record, and with what guarantees?

These questions require some forethought and research, but they will help you decide on the technical architecture that most closely matches your needs. Once you know the answers, you can choose between:

  • Mesh
  • Forwarding
  • Mixing
  • Hybrid
Learn more here on how effective scaling resulted in creating an immersive virtual audience experience 

What is a Mesh Architecture?

Mesh depends almost completely on the client’s capabilities. Each client connects directly to every other client, resulting in each client managing (n-1) bidirectional connections, where n is the total number of clients. With 3 clients in a session, each client has to manage 2 separate connections. Since each connection is encrypted uniquely, each client is responsible for encrypting and uploading their media 2 separate times.

For the math-oriented, this type of architecture can be represented as a complete graph, where each vertex is a client, and each edge is a connection. The total number of edges/connections is exponential, equal to n(n-1)/2, which starts out small, but adds up in a hurry.

Since most Internet connections are asymmetric (download bandwidth > upload bandwidth), upload bandwidth can become a limiting factor, especially if we’re using data-heavy video. Having to encrypt each media stream once for every connection doesn’t help, especially on mobile.

That said, mesh requires no server infrastructure beyond the requisite signalling and TURN server(s), so for applications where sessions typically involve 2-3 clients, mesh is an excellent, low-cost approach. PSST! Both our products, LiveSwitch Cloud and LiveSwitch Server, offer mesh network capability.

What is a Forwarding Architecture?

Forwarding depends on a selective forwarding unit, or SFU, which acts as an intelligent media relay in the middle of a session. Every client connects to the SFU once to send media, and then once more for every other client, resulting in each client managing n unidirectional connections, where n is the total number of clients. With 5 clients in a session, each client has to manage 5 separate connections. One of those connections is reserved for sending media, while the others are exclusively for receiving media.

The total number of connections in this architecture is n2. While this is more than a mesh architecture, it is far more scalable for your clients. It plays well into the asymmetric nature of most Internet connections by requiring each client to upload only once. Related to this, you are also only encrypting once, which alleviates pressure on the device itself, especially on mobile.

One of the big advantages forwarding has over a mesh architecture is that it can employ various scaling techniques. Because it acts as a proxy between the sender and receiver, it can monitor bandwidth capabilities of each leg and selectively apply temporal (frame-rate) and spatial (resolution) scaling to the packet stream as it moves through the server.

What is a Mixing Architecture?

Mixing depends on a multipoint control unit, or MCU, which acts as a high-powered media mixer in the middle of a session. Every client connects to the MCU once, resulting in each client managing just a single bidirectional connection, regardless of the number of other clients present.

As with forwarding, mixing can take advantage of scaling techniques. By applying temporal and spatial scaling to the output of the audio and/or video mixer(s). We can adapt quickly to changing conditions along the network routes to individual clients, keeping the quality as high as possible and without affecting other clients in the session.

For applications with large numbers of active participants. like virtual classrooms, or cases where devices are particularly bandwidth- and resource-constrained, this is a great approach, albeit a potentially expensive one in terms of server cost.

What is a Hybrid Architecture?

Hybrid architectures are, as their name implies, a combination of mesh, forwarding, and/or mixing. In a hybrid environment, participants can join a session based on whatever makes the most sense for the session or even for a particular endpoint. simple two-party calls, a mesh setup is simple and requires minimal server resources. small group sessions, broadcasts, and live events, forwarding will better meet your needs. larger group sessions or telephony integrations, mixing is often the only practical option.

Hardware Requirements to Scale Your WebRTC Application

No matter which architecture you choose, keep in mind that you will always need:

  • A signaling server (for registration and presence, e.g. SIP)
  • A TURN server (for network traversal, e.g. coturn or LiveSwitch’s TurnServer)

Both of the above are available with LiveSwitch Cloud and LiveSwitch Server.

With a couple signaling servers and a couple of TURN servers to support high-availability, you’re looking at a minimum of 4 servers to start. You’re up to 6 servers once you throw in a load balancer and a back-end database or caching service.

When selecting your server hardware, we recommend a general-purpose or compute-optimized server for signalling and a network-optimized server for TURN. If you’re using Amazon Web Services, the M- and C-class servers are excellent choices. If you are using Azure, the A-class servers that are compute- or network-optimized are the way to go.


The Ultimate Guide to WebRTC

What is WebRTC

Web Real-Time Communication (WebRTC) is both an open-source project and specification that enables real-time media communications like voice. Video and data transfer natively between browsers and devices. This provides users with the ability to communicate from within their primary web browser. Without the need for complicated plug-ins or additional hardware.

The WebRTC project was first announced by Google in May 2011. As a means of developing a common set of protocols. For enabling high-quality RTC applications within browsers, mobile platforms and IoT devices. At the time, Flash and plug-ins were the only methods of offering real-time communication. Two years later, after considerable work, the first cross-browser video call was established between Chrome and Firefox. Since then, support for WebRTC in the developer community has skyrocketed as more and more organizations. Add their support for the specification. Today, WebRTC is available natively (to varying degrees) in Chrome, Firefox, Safari, Edge, Android. & iOS and is a widely popular tool for video calling.

Gear - Icon WebRTC APIs

There are 3 primary components of the WebRTC API and each plays a unique role in WebRTC specification:

MediaStream (GetUserMedia):Diagram - WebRTC API-04

The MediaStream API provides a way to access device cameras and microphones using JavaScript. It controls where multimedia stream data is consumed and provides some control over the devices that produce the media. It also exposes information about devices able to capture and render media.


The Peer Connection is the core of the WebRTC standard. It provides a way for participants to create direct connections with their peers. Without the need for an intermediary server (beyond signaling). Each participant takes the media acquired from the media stream API and plugs. It into the peer connection to create an audio or video feed.  The PeerConnection API has a lot going on behind the scenes. It handles SDP negotiation, codec implementations, NAT Traversal, packet loss, bandwidth management, and media transfer.


The RTCDataChannel API was set up to allow bi-directional data transfer of any type of data. Media or otherwise – directly between peers. It was designed to mimic the WebSocket API, but rather than relying on a TCP connection which although reliable is high in latency and prone to bottlenecks. Data channels use UDP-based streams with the configurability of the Stream Control Transmission Protocol (SCTP) protocol. This design allows the best of both worlds: reliable delivery like in TCP but with reduced congestion on the network like in UDP.

Connections - Icon Establishing Connections

Before a peer-to-peer video call can begin, a connection between the two clients needs to be established. This is accomplished through signaling. it falls outside of the realm of the WebRTC specification but is the vital first step in establishing an audio/ video connection.


That allows two endpoints (senders, receivers, or both) to exchange metadata to coordinate communication in order to set up a call. For example, before two endpoints can start a video call, one side has to call the other, and the called side has to respond. This call-and-response message flow (also known as offer-answer message flow) contains critical details about the streaming that will take place – the number and types of streams, how the media will be encoded, etc. – and is often formatted using the Session Description Protocol (SDP), a standard format used by many real-world systems, including VoIP and WebRTC.

This is needed for two reasons:

  1. Generally, the peers do not know each other’s capabilities.
  2. Generally, the peers do not know each other’s network addresses.

NAT Traversal – ICE, TURN and STUN

Once the initial signaling for a streaming connection has taken place, the two endpoints need to begin the process of NAT (Network Address Translation) traversal. When NAT assigns a public address to a computer inside a private network it can cause difficulties for setting up a real-time video connection. NAT Traversal is a method for getting around the issues associated with IP address translation.

In a WebRTC-enabled video call, unless the two endpoints are on the same local network, there will be one or more intermediary network devices (routers/gateways) between the two. There are three key specifications that are used in WebRTC to overcome these hurdles:

  • Interactive Connectivity Establishment (ICE) – ICE is used to find all the ways for two computers to talk to each other. It has two main roles, gathering candidates and checking connectivity. guarantees that if there is a path for two clients to communicate, it will find it and ensure it is the most efficient. makes use of two protocols – STUN and TURN. 
  • Session Traversal Utilities for NAT (STUN) – STUN stands for Session Traversal Utilities for NAT and is a lightweight and simple method for NAT Traversal. STUN allows WebRTC clients to find out their own public IP address by making a request to a STUN server. 
  • Traversal Using Relays around NAT (TURN) – The TURN server assists in the NAT traversal by helping the endpoints learn about the routers on their local networks, as well as blindly relaying data for one of the endpoints where a direct connection is not possible due to firewall restrictions.


Before sending the media over a peer connection, it has to be compressed. Raw audio and video is simply too large to send efficiently in our current Internet infrastructure. Likewise, after receiving media over a peer connection, it has to be decompressed. A media codec (coder-decoder) does exactly this.

WebRTC has mandated three audio codecs and two video codecs:

  1. Audio – PCMU (G.711μ) running at 8,000Hz with a single channel (mono).
  2. PCMA (G.711a) running at 8,000Hz with a single channel (mono).
  3. Opus running at 48,000Hz with two channels (stereo).
  4. Video – VP8.
  5. Video – H.264/AVC using Constrained Baseline Profile Level 1.2.

Future media codecs like VP9 and H.265 could be added to the WebRTC standard at some point in the future, but for now, are not mandatory. RTC experts such as LiveSwitch’s Professional Services team are often able to add additional custom and future codec support to meet any customer’s requirements.

Signalling - Icon WebRTC Topologies

The peer-to-peer (mesh) topology is the only connection type that is covered in the WebRTC specification. However, there are many use cases where a mesh topology is insufficient. Server-based topologies can help address these drawbacks and are often used within the world of WebRTC for transferring media. The best topology for any given application depends largely on the expected use cases, as each one has its own unique set of benefits and drawbacks.

Peer-to-peer (Mesh)

Diagram - Selective Forwarding-04

In a peer-to-peer or mesh topology, each participant in a session directly connects to all other participants without the use of a server. This type of connection is perfect for small video conferences as it is the lowest cost and easiest to set up. However, when conferences grow, maintaining direct connections between all participants becomes unsustainable as it can become too CPU intensive. Since the connections are direct between peers, a mesh topology doesn’t lend itself well to recording.

For these reasons, a mesh topology is best for simple applications that connect 2 to 3 participants, where low latency is important, and where recording isn’t required.

Examples of potential use cases include:

Selective Forwarding (SFU)

Diagram - Selective Forwarding Units

In a selective forwarding topology, each participant in a session connects to a server that acts as a selective forwarding unit (SFU). Each participant uploads their encrypted video stream one time to the server. The server then forwards those streams to each of the other participants. This reduces latency and also permits things like transcoding, recording, and other server-side integrations such as SIP which would be much more difficult in a peer-to-peer connection.

The topology is not without its limits. While having a single upstream connection makes it more upload-efficient than a mesh topology, having multiple downstream connections means each client will eventually run out of resources once a certain number of participants is active in the session.

For these reasons, a selective forwarding topology is best for applications that connect 4 to 10 participants, where low latency is important, or where recording is required and integrity is critical. This topology is generally considered the most balanced.

Examples of potential use cases include:

Multipoint Control (Mixing)

Diagram - Multipoint Control Unit-04

In a Multipoint Control Topology, each participant in a session connects to a server that acts as a multipoint control unit (MCU). The MCU receives media from each participant and decodes it, mixing the audio and video from the participants together into a single stream which is in turn encoded and sent to each participant. This requires less bandwidth usage and device CPU but it does require additional server CPU for mixing audio/video into single streams. MCU’s are also a great option for dealing with poor network conditions as it provides the lowest possible bandwidth usage for each individual participant.

For these reasons, a multipoint control topology is best for large-scale applications that connect large numbers of participants, or poor network conditions, or where recording is required and integrity is critical.

Examples of potential use cases include:

Hybrid Topology

Hybrid architectures allow you to maintain a mix of Peer-to-Peer, Selective Forwarding, and Multipoint Control (Mixing) architectures. In a hybrid environment, topologies can change as participant counts increase and decrease. If recording is critical, for example, starting with a selective forwarding topology and then switching to a multipoint control topology around the 10-participant count could make the most sense. If cost is more important than the integrity of recording, your application could start with a mesh topology and graduate as needed. Our LiveSwitch Server stack is a great example of a hybrid topology and is one of the few hybrid Media Servers on the market today.

Security - Icon WebRTC Security

It is often asked, “Is WebRTC secure?” In a word…yes. WebRTC is secure and employs a number of security measures to ensure your data remains secure. These include:

Browser Protection

As we already know, WebRTC is enacted directly between browsers without the need for plugins. This makes WebRTC inherently safer, because it provides an extra level of protection against malware or other undesirable software installations that may be disguised as a plug-in. Further, because WebRTC is offered as a part of a browser, any potential security threats or vulnerabilities tend to be addressed quickly via auto-updates from the browser vendors.

Media Access

The WebRTC specification has addressed potential concerns to allowing access to media resources by requiring explicit permission for the camera or microphone to be used. It is not possible for a WebRTC application to gain access to a device without consent. Furthermore, whenever a device is in use, it will be indicated in the clients UI and on their hardware.


Encryption is a mandatory part of WebRTC and is enforced on all parts of establishing and maintaining a connection. The preferred method for this is to use perfect forward secrecy (PFS) ciphers in a DTLS (Datagram Transport Layer Security) handshake to securely exchange key data. For audio and video, key data can then be used to generate AES (Advanced Encryption Standard) keys which are in turn used by SRTP (Secure Real-time Transport Protocol) to encrypt and decrypt the media. This acronym-rich stack of technologies translates to extremely secure connections that are impossible to break with current technology. Both WebRTC and ORTC mandate this particular stack, which is backwards-compatible and interoperable with VoIP systems.

Addon - Icon WebRTC Add Ons

While the basis of WebRTC has historically been peer-to-peer video conferencing, there are many promising add-ons that can help make WebRTC even more powerful as a real-time communications tool.

WebRTC and Broadcasting

broadcasting-telephonyWhen combined with efficient server scaling, WebRTC can be used to deliver sub-second latency broadcasts to large audiences. With plugin-free support now from every major browser vendor on desktop and mobile combined with intelligently designed Media Server clusters, it’s possible to scale to thousands and even millions of concurrent users while maintaining just milliseconds of latency. 

WebRTC and Telephony – SIP & PSTN

VoIP-based systems and the public switched telephone network (PSTN) are still fundamental components in many enterprises and often include large historical investments into PBXs, gateways, SBCs. While the traditional landline may be slipping away, mobile phones are still ubiquitous, and VoIP deployments in businesses are still standard. Because of this, it’s imperative for some applications for users to be able to dial into an active WebRTC-based session from a phone or have their phone ring when they are invited to join.

To do this, you need a gateway or switch that can speak the protocol used by VoIP phones everywhere – the Session Initiation Protocol, or SIP for short. Open source products like Asterisk and FreeSWITCH, which support WebRTC, can be helpful for small-scale deployments. Leveraging a flexible WebRTC stack such as LiveSwitch Server or Cloud is crucial for the creation of a seamless user experience when integrating such systems. 

Rocket Ship - Icon Launching a WebRTC Project

Before you can jump into a WebRTC project it is important to have a good understanding of your organization’s needs, current infrastructure and possible limitations. Having a good understanding of your present state and future needs will allow you to determine what options you have for developing your own video conferencing platform.

Do you need a Media Server?

Before you can fully explore your options, you need to have a good understanding of your session requirements. Particularly, what is the maximum number of users that need to be connected in a session at any given time, and what are the capabilities of the network and devices you expect them to connect from?.

If you only need to connect two or three people in a video conference and the users are all expected to have powerful devices on high-speed uncongested networks then a Media Server may not be required for the success of your application. If you need to connect 4 or more participants or if you will be connecting participants in remote areas with older laptops or smartphones, then a Media Server is necessary. It is important to note that session needs often change over time, so consider carefully whether you might need to host larger sessions in the future.

Do you want to host your application in the cloud or on-premises?

If you determine a Media Server is required, your next step is to decide whether you want to host your application in the cloud or on-premise. Each option is valid depending on your specific requirements.


Many commercial WebRTC-based video conferencing products on the market today are cloud-based offerings. In general, clouds are great options for organizations that are looking for a solution that can be easily deployed and can be scaled up quickly with minimal oversight from your team. It is important that organizations considering cloud-based video conferencing options carefully check the data security. Protocols of the provider to determine the risk and whether the offering complies with data protection laws including GDPR. For a fully secure and fully managed cloud-based product, check out LiveSwitch Cloud.


Media Servers can also be hosted on-premise. This is a great option for organizations that are seeking maximum control over their data. On-premise solutions often appeal to those in risk-averse industries like governments, financial institutions or healthcare.   

It is important to note that “on-premise” can be a bit of a misnomer. While some Media Servers are physically hosted on your own premises. Others could be hosted in a private cloud controlled by your operations team. The difference is your organization has the ability to choose your own. Cloud infrastructure provider based on your own unique specifications and risk tolerance. LiveSwitch’s Server SDK is completely compatible with all cloud infrastructure providers including AWS, Azure, Oracle, Digital Ocean and more. In some instances, this could be a more cost-effective option as you are dealing with the cloud provider directly. Rather than through a third party. However, owning, operating and maintaining your own Media Server on-site also. Implies costs that may or may not work with your business model.   

What type of WebRTC-enabled video conferencing will best match your needs and the expertise you have in-house?

There is a wide spectrum of options out there for creating a video conferencing system; from creating it from scratch using open-source, to ready-made platforms and everything in between. Below we will go through the 5 most common types of services.


Open Source

The first option available to developers is to build your own platform from scratch using open-source code. The source code for WebRTC is freely available to the developer community to use or modify as they see fit. Creating your own application with the open-source. Code available can be a good option if you have enough skilled WebRTC developers. Available to take on the project (there are less than 12,000 worldwide). Have the time to devote to the applications development, are comfortable sourcing media and signaling servers. And are in a position to navigate the uncertainties that come with any development project.

Commercial SDK

A software development kit (SDK) is a set of tools provided by hardware and software providers. That are used for developing applications. SDKs operate on the client-side of an application and are usually comprised of application programming interfaces (APIs). Sample code, and documentation. Using an SDK to build your video conferencing. Application is a good choice for developers who are looking for more control over their solution. It is also ideal for organizations that wish to manage their own data centers or cloud deployment. LiveSwitch Server and LiveSwitch Cloud are great examples of commercial SDKs that provide varying levels of WebRTC capabilities that can be built into applications.

Software as a Service (SaaS)

Some organizations may wish to outsource pieces of their WebRTC development to others.

These pieces are offered as a service, also known as a Software as a Service (SaaS). SaaS is a cloud-based software solution that hosts applications and makes them available to customers over the internet. It is possible to combine an SDK or open source project with some SaaS offerings. Some examples of pieces that may be purchased as a SaaS include TURN servers, NAT Traversal, and signaling servers. LiveSwitch Cloud includes these pieces that can be customized easily all within its web-based platform.

Communications Platform as a Service (CPaaS)

CPaaS stands for Communications Platform as a Service. A CPaaS refers to a cloud-based platform that enables developers to add real-time communications features. Like voice, video and messaging capabilities in their own applications without needing to build back end infrastructure and interfaces. Using a CPaaS is a great option for those who are looking to reduce. Their time to market and their upfront. Development costs while maintaining a large degree of control over the design and development of their solutions. As it is a cloud-based offering. Customers need to do their due diligence to ensure the cloud meets all security requirements. LiveSwitch Cloud is a great option for anyone who is looking for a highly flexible CPaaS platform with advanced functionality and analytics. 

Ready-Made Platform

The last option is purchasing a turn-key video conferencing solution. These solutions are designed to be fully complete and are ready for use by the average consumer on purchase. This can be a good option for organizations that don’t have access to. Software developers and who are OK with paying. A little more for a product with limited flexibility.

If you are unsure of what WebRTC option is right for you, consider investing in an architecture assessment. This is a great first step for those who are looking for a path forward for their WebRTC project.


Mobile App Development Process in 2021 – 7 Stages of App Development

Mobile App Development Process – 7 Stages of App Development
Let’s dive into each of the above-mentioned steps of the mobile app development process.

STAGE 1. Choosing a partner – select a company to design and develop your app
Decide if you want to build your app in-house, or outsource its development. This article may help you: Inhouse vs. outsourcing software development. If you decide to outsource your product creation, you need to know how to choose a proper app development company for your project. How to verify if a company you want to choose, is trustworthy? We recommend you to:

Use or other platforms for B2B buying, AppFutura, GoodFirms, ContractIQ – use platforms that will help you to make an initial selection of companies that meet your requirements.
Analyze pre-selected companies
Check opinions about them, as well as their portfolio. Ask questions like:
Do they have experience in creating products similar to yours?
Did they work with partners from many countries and different industries?
Do they work with start-ups, big companies… or both?
Do they use new solutions and technology?
Analyze the estimations you receive
It is worth to get estimations from more than one company and compare them. If you get two totally different estimations, it is worth checking how each team made their respective figure.
Did you deliver the same information and documentation to both companies?
Ask the companies on which assumptions they based their forecasts. Does the lower estimation contain all the crucial elements included in the higher one?
Did they ask questions to learn more about your app idea?
Does the estimation contain the time for team meetings?
Does the estimation contain the time for Quality Assurance (e.g. writing tests)?
Did the companies take into account the risk of unforeseen events?
If your app’s design demands some non-native solutions, is this considered in the estimation?
If your product is a typical kind of app, like e-commerce or m-commerce, but you want it to have some untypical features, check if they have been considered in the Estimations.
Read also: How much does it cost to develop an app?
Make sure the code will be written in English
Make sure the code will be hosted on Code Repositories Hosts
E.g. Bitbucket, GitHub, so you can have access to the code and be sure that it is safely stored.
Verify the Independent Contract Agreement
Verify the contract you get carefully and make sure to consult with a lawyer about it. Below, we’ve listed for you a few important elements that should be included in a contract. We are not writing about some obvious elements, like personal data of parties, but rather factors more specific to software houses.
Confidentiality: Make sure that the contract contains a clause about confidential information. Your partner should commit himself or herself to not disclosing any information about your project that is not public yet. –> Download for Free your Printable NDA (PDF)
Intellectual property: You should have the rights to everything the software house produces. The contractor shall execute and deliver such further instrument(s) and take such action(s) as may reasonably be required to complete the assignment of intellectual property rights in the Deliverables to Company’s sole and exclusive ownership.
Choice of Law: The contract should indicate a dispute resolution place. That is especially important if the software house is from another country. Probably, your partner will want to choose the judiciary of his country. We would recommend compromising and choose the laws of another country, with the jurisdiction you know, e.g. the United Kingdom.
Advance payment: We recommend that the advance payment should not exceed the cost of the team’s work for one month. In case a contractor must incur significant expenditure (e.g. for hardware or licenses) at the beginning of the project, a higher advance payment can be reasonable.
Payment deadline: The contract should regulate the consequences of delays in payments. What is the acceptable delay? After how many days will interest be charged? After how many days can the development team stop work? Contrary to appearances, such a clause secures you.
Conditions for terminating the contract: It is safe to set a notice period of about 15-20 days.
Time & Material – in this type of contract, there is no need to specify an exact deadline. You decide when the app is ready. Your Feedback after each iteration is implemented up to date.
Fixed Price – the contract contains a schedule of partial deliverables. What is more, it is worth setting the time for you to give feedback for every iteration, as well as for the team for implementing that feedback.
In this article – Mobile App Development Process – Stage 1. Choosing a Partner – you will find examples of contractor agreement fragments that should be included in your contract. Read also: Time & Material vs Fixed Price – Comparison for App Owners.

Let’s sum up Stage 1 of the mobile app development process:

Mobile App Development Process – Stage 1Mobile App Development Process – Stage 1
STAGE 2. Product Discovery – define what you want to create, for who and why
Before you start your mobile app development process, it’s necessary to clarify your app’s vision – we call this phase Product Discovery. This is the key to your app’s success. The foundation of Product Discovery is a constant testing of solutions and ideas, as well as learning how to adapt them to the user’s needs. It also ensures that not only you are aware of the end-users’ needs, but your development team knows your goals and is able to deliver your ideas.

Here are the following areas you should focus on during Product Discovery:

Establishing a strategy. What is your goal? What outcome do you want to achieve?
Targeting potential users and their problem. Who is the user? What kind of problems do they have? How can we help them?
Ideating solutions. How can you solve the problem? What will be the outcome of such a solution? What is the best solution?
Prototyping. What is my user’s experience? Do I like the solution?
Reviewing ideas. Are your ideas good enough? What do my users think about them? Can I really solve their problems?
Narrowing down the solutions. Which ideas are we going to implement?
Prioritization. Which features are the most crucial in the app? What are the features to be implemented first?
Planning. What is the scope of our MVP (Minimum Viable Product)? How can I measure the end result to determine if the goal has been met?
In this article, you can read more detailed description of each of the above-mentioned Product Discovery elements.
You can find the answers by yourself, with your team, or during a Product Design Workshop organized by an outside app development company – it’s your choice.

The recommended tools that can help you to clarify the idea of your app are Product Canvas (PDF print), Personas (PDF print), Event Storming, User Journey Map, and Prioritization Chart (PDF print). You can find a description of all of these tools in this article: Mobile App Development Process – Stage 2. Product Discovery.

If you already know the answers, and your vision is clear, this is great! Yet it’s simply not enough to have them in your mind. Write them down and confront them with others – talk to people from your team, employees, or just your friends. They should understand what it is about.

How about starting development without clarifying your vision? Product Discovery is an optional process but would it make sense to start costly development without thorough research? In the Theory of Quality Management, we have the “1:10:100 rule”, which states that prevention is cheaper than correction, and correction is cheaper than failure. Product Discovery costs you nothing compared to releasing a useless application.

In short, Product Discovery is the app development phase where we are focused on building the right thing, as opposed to building the thing right.

Please note: it’s worth to consider leal and security issues at this stage. Read more:

Let’s sum up Stage 2 of mobile app development process::

Mobile App Development Process – Product Discovery Phase
STAGE 3. UX / UI app design – determine how your app will work and look
Let’s start with an explanation, what do UX and UI mean. To put it simply: UX (User Experience) is how an app works UI (User Interface) is how it looks. Well designed UX and UI are very important from a business point of view. At the end of the day, they influence the retention rate. If your apps’ user experience will be enjoyable and flawless, and the design of the app will create a positive impression on its users, they will love it, and use it.

This stage of mobile app development process includes creating:

Mobile App Development Process – Stage 3. UX/ UI App Design
User Journey Map
You (alone or with your development team) create a User Journey Map. It is a visualization of the user flow through your app. It tells the story of the user’s experience. At Droids On Roids, User Journey Map takes the form of the drawn schema on the wall (we wrote about it here), or we draw it using Figma. It is usually a part of Project Discovery, but we present it here to show you that is crucial to create wireframes and user interfaces.

Wireframes (UX)
Designers create Wireframes – digital, simplified visual concepts of the future app. They lay out the structure, hierarchy, and relationship between the elements that make up the product. It is a kind of app’s backbone.

Clickable Prototype Mobile App Development Company PolandWireframes Mobile App Development Company PolandWireframes Mobile App Development Company Poland
Then, designers use Wireframes to create a Clickable Prototype – a dynamic, interactive model of your app. It simulates a real-world product. An example of a Clickable Prototype:

Design (UI)
Designers work on the visual language of your app, its style guide, User Interface, and motion design. You get mockups showing the final look of your app, and videos presenting motion design (animations & screen transitions) in your app.

App Design – Mobile App Development Company Poland
To sum up, even if your app idea is great, but its interface and UX design will be of low quality, you won’t succeed. Make sure that the UX and UI Design processes run in a thoughtful way. Be engaged in each stage of designing your product, so the team can shape the final designs according to your expectations. And last, but not least – remember to put your app’s users in the center of your thinking.

STAGE 4. Project kick-off & setup – last preparations before the start of app development
App Development Kick-off has a significant influence on the successful cooperation with your software partner. In short, it’s time to define your role as a Product Owner and to clarify every role in the team. What is more, Project Kick-off means also setting the rules you want to follow, and planning the next steps. Kick-off may have different forms, at Droids On Roids we organize a Kick-off meeting with every client (remote, or face-to-face), it takes around 2 hours. An example of how kick-off may look:

Mobile App Development Process – Kick-off Phase
When App Development Kick-off is completed, the first Sprint starts. It is also the moment when developers set up your project.

How do the developers set up your project?
These 6 elements are specific for mobile app development, but in the case of web apps, they look similar (with the exception of the third point).

Creating a repository for a project at GitHub or another web-based hosting service. It means creating a space dedicated to your project on the cloud-hosted platform, where all versions of your code will be safely kept and archived.
Continuous Integration setup. Every new piece of code has to be checked before it is merged into the project. It’s checked manually, but also with automated tests run by special platforms like Bitrise, CircleCI, or Jenkins. The process of automating the build and testing the code every time a team member commits changes is called Continous Integration. The second role of CI platforms is pushing the app versions to Google Play / Apple Store and allowing running tests by users. At Droids On Roids, we use Bitrise.
Setup of the beta distribution tool on the CI platform. App Center, Fabric – these are a few examples of tools that help you to collect live crash reports, get feedback from your app’s users, or distribute your betas. To say simply – they take care of the quality of your product.
Choosing a code architecture, libraries & SDKs. Developers choose the code architecture for your project (e.g. MVP, MVVP, VIPER, MVC, Clean Swift). Code architecture can be compared to the construction of a building. It is not visible outside when the building is finished, but it decides about the shape of the object and its’ solidity.
What is more, developers choose also libraries & SDKs (Software Development Kits) which they will use in your project. In other words, SDK is a set of software development tools useful in app development. Read also: Pros and Cons of Using Third-Party Software in Your App Development.
Setup project in IDE (Integrated Development Environment). Developers set up your project in a program that they will use to write the code – e.g. Android Studio for Android Apps, or XCode for iOS Apps. To the program, they add also outside SDKs or libraries that will help them to optimize their work.
Register the app in Google Play Console, Firebase API Console, and other services if needed. If your app will use some third-party party components (e.g. Google Maps, push notifications), it must be registered on the suppliers’ services.

Let’s sum up Stage 4 of the mobile app development process::

Mobile App Development Process – Stage 4
STAGE 5. App development with Quality Assurance
That’s the phase, where developers start to write the code and produce your product. How do they do that? Mobile app development is an iterative process. You have probably heard the term Sprints or Scrum. This basically means that you break up all development work into smaller milestones and develop your mobile app in a series of cycles. Each cycle will include refinement, planning, development, testing, review, and retrospective.

Sprint Refinement (Product Backlog Refinement) is the act of keeping the backlog updated, clean, and ordered. A backlog is an ordered list of everything that is known to be needed in the product. Refinement should be an ongoing process. However, it is useful to have a planned meeting for Refinement.

For example at Droids On Roids, we discuss the tasks from the top of the Product Backlog, making sure that their acceptance criteria are clear, and estimating them. Then, during the Planning Meeting, there is less to review, and planning is easier.

Only the first Sprint starts with Refinement – we need to prepare backlog before the first Planning. Later, every Sprint will start with the Planning meeting.

Sprint Planning is max. 2 hours meeting (for 1-week Sprint). Its’ goal is to decide which tasks should be included in the upcoming Sprint. The team talks about the things to do, making sure that the acceptance criteria for each task are clear and accepted by everyone. The Product Owner (you) joins this meeting (for example on Skype) so he or she takes part actively in planning the next iteration.

Developers are writing the code and implementing the features planned for the Sprint, QA Engineers are writing automated tests. It’s good when developers practice Code Review. Code Review is not necessary for developing a crash-free app but it is a good practice if you want your app to have code written in a clear and transparent way, so in the future other developers can easily improve the app and continue working on the code.

Testing (QA)
During development, we use a platform called AppCenter. It allows us to privately and securely distribute the in-development version of the app to testers, clients, and other developers. The platform automatically notifies users of new builds (so everyone is testing the latest version), provides crash reporting and ensures only approved testers have access to your app.

Quality Assurance (or simply QA) is a way of preventing mistakes in developed applications and avoiding problems when delivering them to users. It is integrated into every stage of development. This is an example of how Quality Assurance can be integrated into the app development process:

Mobile App Development Process – Continuous Integration
Coding – developer writes the code, QA specialist writes automated tests.
Pull Request – developer tells others about a new part of the code.
Execution of automated tests – automatic tests that check whether new changes didn’t break any already implemented functionalities. It consists of:
Static Code Analysis – a code is checked by a special program (Lint, Sonar), which verifies if the code meets the good standards set by our development team.
Executing Unit Tests – automated tests that validate if each unit of the software performs as designed.
Executing UI Integration Tests – automated tests that check if the app components are correctly integrated.
Virtual Device Testing – we use it to find crashes in Android apps. It simulates a real app user.
Code Review – every piece of code written by one developer is approved at least by 1 another dev.
Deployment – the latest alpha/beta release is delivered to the client and testers.
Manual Tests – manual testing of the app based on specified use cases. Made by QA specialists.
The feature is done
The process is repeated many times during development. Read also: Mobile Security Testing. Make the First Step!

Below you can find a list of good practices in Quality Assurance that we recommend you to consider while working with an outsourced development team:

First, make sure that your partner has Quality Assurance engineers who will take care of the highest product quality at every development stage.
The development team should have a dedicated specialist who will ensure QA for your project holistically. Why? He will have a map of the whole project in his mind. For work hygiene, pair-testing is fine, but frequent changes of testers carry the risk of mess and chaos in the project.
You are not the one who should pick up basic errors and differences between what is in the requirements and what you got.
Developers are not testers. Your partner says that they don’t have a Quality Assurance specialist, but it is OK because a developer will test the app? Well, not exactly. A developer who wrote the code shouldn’t check his own work. It is harder for an author to see their own mistakes. What is more, developers can consider something not as a mistake because they understand what they have written. An extra pair of eyes is always helpful.
QA should be ensured from the very beginning. Don’t put QA off until later. Even small errors in the early stages of development can cause more complex complications in the future. The sooner you start with QA, the fewer troubles you will have in the future.
You should have insight into the output of the tests. Which features have been tested so far? What bugs have been found? As an app owner, you should have insight into testing progress. There are many tools that can be used to easily track and follow the status of tests, e.g. Testlink, QA touch, TestRail, or Jira.
The tests should be run on different types of devices because your product should work perfectly not only on one type of smartphone. A great solution is Smartphone Test Farm (STF) – it is an app that allows developers to:
control and manage real-time testing on many devices remotely from their workplaces
run automated tests using dedicated software like Bitrise that enables testing apps on many devices at once.
QA in mobile app development process – STF in action
STF in action

During the Sprint Review, the Scrum Team and stakeholders collaborate about what was done in the Sprint. A Sprint Review is held at the end of the Sprint to inspect the Increment (all tasks completed during the Sprint). It takes up to 1 hour in case of a 1-week Sprint. A great practice is if, after Review, your development team send you:

An app demo build (so you can check if the created app fits your expectations)
A detailed review of what’s been done
Information about eventual difficulties or additional work that has been done
Information about how many hours the team worked on the project during the Sprint
According to the PO’s preferences, he or she can take part in the Review meeting, or just get the above-mentioned information with an E-mail.

Retrospective meeting (about 45 m for 1-week Sprint) occurs usually after the Sprint Review. During this meeting, you and the team plan together ways to increase product quality by improving its’ work processes. The purpose of the Sprint Retrospective is to:

Inspect how the last Sprint went with regards to people, relations, process, and tools
See what went well and define potential improvements
Create a plan for implementing improvements
Please read the whole article describing app development with Scrum – and learn Scrum Sprint Workflow with all Scrum events.

To sum up this stage – all features are firstly planed, then implemented and tested while the Continous Integrations process, where Quality Assurance is integrated at every step, in the end, they are accepted by the Product Owner. The entire application is built in this way – in repeated cycles – of planning, coding, and testing, reviewing, and improving the process and the product. This approach gives you great flexibility – it makes it easier for you to monitor the process, the product, and introduce changes easily.

STAGE 6. Preparation and publishing of the app on Google Play Store and Apple Store
When the first version of your mobile app is ready, it is time to publish it. Your partner should assist you to upload your Android app on the Google Play Store, and your iOS app on the Apple Store. It is also a part of the app development process. The company should guide you through the app setup on the stores regarding the marketing materials, description, and legacy issues.

Google Play
Releasing includes gathering & uploading promotional materials (like graphics, videos), configuring options, and uploading assets required by law (like privacy policy, geographic and/or age restrictions, pricing), and continuous deployment configuration (this part is optional but recommended). The last step is publishing the release version of your app.

Apple Store
The first step is to fill in the basic information about the app on the Product Page, such as the app’s name, icon, description, keywords, and privacy policy. If your app supports Dark Mode, consider including at least one screenshot that showcases what the experience looks like for users.

Then, developers upload the build of your app using Xcode. The app might then get tested using the TestFlight tool. The same build of the app that was tested can be then assigned to a specific version of your app. The next step is to upload screenshots of your app taken on different devices, fill in all the missing legal information, and submit the app for review. Apple employees will test your app and see whether it complies with the rules of the App Store. This might take around 2 days.

STAGE 7. Post-development phase – app maintenance & further development
During app maintenance, the development team implements app monitoring tools (e.g. Crashlytics, Google Analytics, Firebase) to your product. Thanks to these tools team can detect any crashes, follow app’s statistics, and plan product enhancements. The post-development phase includes also further development of your product – it allows your app to stay attractive, adapt to changing market conditions, and users’ feedback.

Mobile app development process – summary
We hope this article helped you to understand the mobile app development process and it’s all stages – from choosing a partner, and Product Discovery, to app release, and its maintenance. Take the steps outlined in this guide, and you’ll make sure that you’re developing a product that has a perfect market fit.


Flutter 2.2.0 Is Here! 3 Reasons Why It’s Awesome

Flutter 2.2.0 is MAJOR minor update

After the big premiere of Flutter 2, Google has shown that it wants to continue developing the framework, which is one of their many projects (we all know what happens with most of them).

We no longer have to worry about the future of our framework because Google wants to leave a mark in the world of mobile cross-platform for good. Flutter is beginning to mature.

On Google I/O 2021, they announced Flutter 2.2.0. Over 1,000 PRs in flutter/flutter merged and more. Flutter Web, iOS improvements, a new Dart release, new packages, tool improvements and so much more.

In this article, I will show you three changes that in my opinion are important for the future of Flutter developers.

1. Official Docker support and Dart on Google Cloud

We are getting tested and validated Dart images on Docker, which support AOT compilation. Dart on the backend is not something new. We have projects like Aqueduct, Angel or Jaguar, as well as complex server frameworks created by the community.

Having only Flutter developers in a team creating the frontend and backend with one programming language could have its huge advantages.

Everyone has the same knowledge about the project because there’s no division between backend and frontend devs. We write in one common language, so there’s even some space for reusing components.

If we have only one dev (for maintaining the project, for example) that person can easily switch between platforms if required, without waiting for the backend dev to make changes for him or her.

But backends written in Dart are not a popular solution, and you can easily see it by activity in the packages mentioned earlier.

With this update, Google wants to support that approach. They even work with a community on a package that will allow us to use Cloud Functions in Dart, supporting serverless solutions. I hope that this update will trigger the community to return to this topic.

2. iOS performance improvements

This update is not in production use, but in preview. They finally took care of the legendary iOS jank. I’ve seen many tweets or youtube videos saying that Flutter is completely useless on iOS because of this (for example this video).

We, as Flutter developers, know that the problem with compiling shaders happens only in particular cases, so we can avoid increasing rendering performance. But from a user perspective, when it happens it is a serious issue, it can in the worst cases make them remove the application.

Google came up with an idea of caching shaders so they are ready before the first frame. But it was only working on OpenGL. We know this because, with Metal enabled on iOS by default, this issue still exists.

From this PR we can see that the ability to warm up shaders is also going to be available with Metal. If you want to try it, make sure you’re on the dev channel!

The first user experience is crucial from the business point of view. Users can remove your application because of too long loading indicators, bad UX, or non-performant animations. It’s really good to see Google and the community’s cooperation over this problem.

3. Community appreciation

One thing that Google does better than Apple is noticing its community. They do it at every event by organizing social media initiatives. The best clock written in Flutter, sending photos to be displayed on upcoming Google events, creating your own dash avatar, fun Flutter-related filters and so much more.

Community is an integral part of Flutter development. Community is Flutter.

They let developers maintain core widgets, they appreciate some popular packages by adding them to Flutter Favorites, and they also mention some packages in their tutorials!

Google makes you feel that this framework belongs to you, the developers, and not to the stakeholders of Alphabet.

From a marketing point of view, this is the perfect way to develop your product. The more you engage the community, the more feedback you get. The best testers of your product are your users. The same goes with Flutter.

I talk about all of this because, in Flutter 2.2.0, Google also recognized its community.

Do you perhaps know the provider package?

Of course you do!

This package, created by Remi Roussel, is now available to be debugged in DevTools! This is just a magnificent move isn’t it?

The future is bright!

Those are three things that mean that Google is really serious about Flutter and the times when people were wondering when this project will be closed are finally over. We love Flutter at Droids On Roids (we’re an experienced Flutter development company), and we’re very much looking forward to the next updates!


Node.js vs Python: Which backend technology to select in 2021

One must understand that every programming language has its very own set of strengths and drawbacks. Moreover, a single programming language cannot do it all. Certain scenarios need specific programming languages.

In this article, we will take a look at two of the most popular programming languages, Node.js and Python.

During the last couple of years, both Node.js and Python have gained quite a lot of traction. When it comes to Node.js vs Python, the latter stands out as the most popular programming language, whereas the former is excellent for server programming/development.

But before we dive into the differences, let’s understand what Node.js and Python are.

What Is Node.js?

Node.js is predominantly event-driven, which makes it versatile and it adds tremendous efficiency to the project. Its concurrent structure allows it to process several requests at the same time without stopping I/O activities. On both the client/server sides, most developers choose Node.js over JavaScript.

Node.js is ideal for developing real-time smartphone applications since it allows you to edit several modules at the same time.

As per Hostingtribunal, Node.js reduces development costs by a staggering 58%. Netflix, Amazon, Reddit, eBay, and many more use Node.js.

What Is Python?

Python is the most well-known backend developing language with several built-in tools and packages. It is a very simple language and aids programmers in writing clean coding sequences for projects. Python supports various other programming languages as well. Rather than lengthy, replaceable coding lines; with Python, programmers may employ code modules.

It’s so popular that, as per Leftronic, 4 out of 5 programmers state that Python is their primary language. Moreover, Python is among the main languages used by Google.



Which Backend Technology You Must Choose In 2021?

When creating an application, you cannot go about using any programming language you want. There are several situations where Node.js development plays a key role, and then there are situations where Python plays a more significant role.


Source: MindInventory

Understanding which language to use in which situation is the key. Without further ado, let’s compare Node.js and Python based on different criteria:

1. Architecture

The rules for generating modules and connecting them are defined by the architecture of computer languages. To enhance the developing process, you will require a good architecture.

  • Node.jsNode.js development is event-driven that allows for concurrent input and output. When a specific event happens, a particular process is invoked, ensuring that no program stops the thread. The event-driven design of Node.js is ideal for creating chat games and apps on the web.Single Thread Event Loops are used in Node.js’ architecture on the server-side to manage concurrent user requests. Rather than generating many threads to manage the obstructing requests, a single thread is used. Node.js does not require as much memory or resources since just a single thread and is more than enough to handle multiple requests.
  • PythonPython, on the other hand, is not built in this manner. With the aid of specific tools, you may utilize it to create an asynchronously event-driven software. Asynchronous code can be written in Python using modules such as asyncio. However, most Python frameworks do not include this package; thus, it requires some extra effort.Asynchronous programming is not integrated into Python’s architecture to provide input-output capabilities. Whenever a blocking request is in progress, you can’t perform any more unblocking requests. This functionality requires unique modules, which aren’t really accessible in the majority of the Python frameworks.

The Verdict: Owing to its receptive architecture, Node.js takes the point here.

2. Libraries

This refers to a set collection of modules that include several different features. Developers can incorporate these features to help them write new codes. It makes the process of coding an easy one.

  • Node.jsNPM – the Node Package Manager – manages libraries and packages in Node.js. It’s among the largest software library sources. NPM is simple to understand, well-documented, and pretty straightforward to use.With Node.js, you can quickly import current code packages that are adjustable for a variety of scenarios.
  • PythonPip, which refers to “Pip installs Python,” is the Python library and package manager. Pip is quick, dependable, and simple to use, making it simple for programmers to learn.It includes 220,000 packages to pick from in various categories, including image processing, data analytics, computation, and more, depending on your needs. Although Python contains multiple libraries, the record-keeping makes installation simple, making it a popular choice among programmers.

The Verdict: Owing to its large library, Node.js is a clear winner in this category.

3. Syntax

To have flexible smartphone app development, you ought to have a user-friendly syntax.

  • Node.jsThe Node.js syntax is almost identical to the one in Python; this means that if you have any kind of experience with Python. Then you will absolutely have no problem writing a backend development code with Node.js.
  • PythonPython’s syntax is frequently cited as its strongest feature. Therefore, computer programmers who code in Python need to generate fewer lines of code than those who work in Node.js. Python’s syntax is straightforward and devoid of curly brackets.The code is significantly easier to understand and debug as a result of this. In fact, Python code is so straightforward that even people without technical experience may understand it. But, once again, it is a matter of personal choice.However, novices will benefit from Python’s syntax since it is simpler to understand and master.

The Verdict: Owing to its simplicity, Python takes the point here.

4. Performance

The responsiveness of the customer’s requests is affected by the speed and performance of the computer languages.

  • It also enables you to make use of technologies like TCP sockets that aren’t available in browsers.Consequently, the event-driven non-blocking design allows for processing multiple requests simultaneously, thereby speeding up the code execution.Finally, Node.js supports single module caching, significantly speeding up app loading and improves responsiveness.

Verdict: Although Python is much simpler to understand, it doesn’t have speed optimization, making Node.js win in this aspect

Without the ability to scale an app, it becomes stagnant.

  • Node.jsYou won’t have to build a massive unified core using Node.js. Conversely, you develop a collection of microservices or modules, all of which communicate using a compact system and run their own processes. The development process is flexible; . To grow it horizontally, you just incorporate more nodes into the existing system. You insert more resources into the nodes if you want to scale it vertically.Lastly, in terms of type, Node.js offers more alternatives as compared to Python. However, Python employs the Global Interpreter Lock; it doesn’t permit multithreading (GIL).Even though Python contains multithreading libraries, it is not “real” multithreading. Moreover, even if you happen to have several threads, the GIL lets Python run only one thread at a given time.

The Verdict: When it comes to scalability, Node.js takes a point.

6. Universality

It refers to the capability of these languages when handling several devices that use web apps.

  • Node.jsBackend development mainly requires Node.js. Similarly, you use javascript for front-end development. Therefore the front-end and back-end utilize the very same computer language.Node.js is capable of handling web pages and web apps on a variety of devices. Because Node.js is cross-platform, a programmer may post a proper desktop app that runs on Linux, Windows, and Mac.

The Verdict: Considering universality, both of them go hand-in-hand.

Final Word

As previously stated, each programming language has its own set of advantages and disadvantages. Some languages may work in a situation, and they may not work as well in others.

Therefore, understanding the goal of your project is essential. You can always choose the language based on that. This approach will also increase your success rates.

So, if you’re working on a project, make sure you are aware of the requirements, features, and benefits you want. After that, make a list of all the needs and then evaluate which language would work better.

This is the way you can get the best result possible.
