Have you found this word scalable when applying for any Mobile App developer job posts?

If not, you can read this post to get an idea of “scalability”.

What is meant by scalability?

Let us try to understand scalability first. Scalability refers to the performance of any web browser or app when users hit searches for the data which the users are looking for. The web application or app should not break when more users are using it. This is what scalability refers to.

Scalable app:

  1. Scalable app refers to the app performance which is rapid and reliable and a greater number of resources or features can be added flexibly by keeping the structure of the central node as such.
  2. Scalability is a very critical condition and it has to be met while developing any app.
  3. The scalable application must not get crashed/damaged or should not stop working when many users are working by feeding the input data for their searches. The servers must not break. The application must not suffer from bottlenecks.

For instance, Facebook is an example where the users reached 1 million just after 11 months of opening. The server was working more than expected bringing a large number of users.

Tips followed to scale an app:

  1. Load testing:

Load testing is the best way to find out the performance of your app. It is one of the easiest means to find out the performance of your web browser and also to get to know how many customers are browsing your site.

  1. Plan:

If you are planning to find out the performance of your browser, then you must schedule the plan a few months in advance to carry out the process so that you can evaluate and fix the bottlenecks and any issues which you might be facing. Planning saves a lot of time for your business. The surge in the number of customers depends on the type of business site you own. It is very much appreciated and advantageous if you include load/performance testing in your continuous integration processes.

  1. Record your test process:

If you record your test scenario using the BlazeMeter Chrome extension for instance for your load testing, you can observe the scaling for high numbers, but it does require time. It is one of the good ideas to find out the traffic for your site. Also, there are many such functionalities similar to BlazeMeter.

  1. Remove unwanted data:

If you want to do a load test, then a certain amount of resources would be used up. But, for huge scaling, a lot more resources would be utilized. It is very much advisable to remove unwanted data so that your resources do not crash or fail while performing load tests.

  1. Canvas test results and engine promptly:

It is mandatory to find out your CPU and memory usage constantly. If the CPU and memory usages have crossed a certain limit, then you are approaching an alert mark that you must not cross. So, constant analysis of reports will help you to know the health of your engine.


I hope the above said tips will help you in the scaling of your app. App developers must definitely incorporate load testing into the integration processes. Load testing not only ensures your business knows about the customer’s surgeon on your website but also your engine health. It is good to perform load testing so that you are aware of any bottlenecks, issues, and weaknesses of your application. You can also add features or remove them on a trial and error basis so that you get a picture of your systems architecture. Hope this article answers all your queries!
