What is back-end development?

Back-end development is a mix of hardware and software, which realize the logic of the site.This is something that is hidden from the user's eyes and occurs outside of his browser and computer.

When our Cloud Ready Teams are working with back-end, there is a range of programming languages we can use, for example Ruby, PHP, Python, Java.

Thanks to back-end, we have an opportunity to create and integrate databases, provide security, create backup and recovery technologies.

Q: How does the front end app in your mobile phone and the application back end interact?

A: It can be described as a circle: the front end application user form sends user’s data request to the back end, where it is processed and returned back as an answer in a clear form.


There are several options for technical solutions for the interaction of the front end and back end:

  • The HTTP request is sent directly to the server, the server makes a search for information, embeds it into the template and returns it as an HTML page;

  • using AJAX (Asynchronous JavaScript and XML) messaging.

    In this case, the request is sent by the JavaScript loaded into the browser, and the response comes in XML or JSON format;Single-page applications that load data without refreshing the page. This can also done using AJAX or Angular and Ember frameworks;

  • Ember or React library helps to use the application both on the server and in the client’s side. Front-end and back-end interact via AJAX and HTML code, which is processed on the server.

As we can see, modern development is a complex and multi-level process, which is divided into two parts: client and server.


In the arsenal of frontend and backend programmers there are a lot of tools which are chosen according to the tasks and complexity of the project.

Both types of development include technical and creative components.

For developing back-end our company has a wide range of technologies: Ruby, .NET, Java, PHP, Node JS, Go, C++, C#, Flutter, React.JS.

With Lifetime Group’s Continuous Development Service you as the customer make sure that your application responds to any interaction correctly all the time, and all the updates and security fixes are done when needed.
