Depending on your product’s goals and functionality you should understand whether to create a cross-platform or native messaging app. The difference lies in the app availability of the app across the majority of platforms simultaneously or individually for each operating system

Both options have their pros and cons. Native app development ensures higher system performance, stability, security but requires more investments.

Server-side of software can be coded in PHP, Ruby, Erlang, and similar. Your software development vendor should advise you of what is more suitable to use in your case.

Also, one of the most common product architecture is a software bundle of LAMP. Linux as the operating system, Apache- web server, MySQL database, PHP as a back-end language.

Alternatively, you can use a PostgreSQL database, Nginx web server, Nodejs, Ruby, or JavaScript for the backend development.

WhatsApp uses YAWS (Yet Another Web Server) for data storing and HTML5 WebSockets to create a solid connection between a server and messenger.

The system uses LYCE/LYME architecture consisting of the open-source solutions to develop highly available and dynamic pages.

To note, Elixir programming and its Phoenix framework are great to utilize for complex and high load projects. These technologies ensure smooth system operation, great efficiency, and the ability to handle lots of traffic.
