Second, Flash is not a preferred choice from a security standpoint.

First, it would ask the users to install a plugin in their browsers which is not a good user experience. Long opened persistent connections are established between the client and the server with the help of Ajax.įlash was dismissed purely due to two reasons. The user interface is naturally written in JavaScript with some PHP used for server-side rendering. The entire system consists of several loosely coupled modules working in conjunction with each other such the web tier, user interface, chat logger, user presence module & the channel cluster. Real-Time Chat Architecture & Technology Stack

The learning track takes you right from having no knowledge in it to making you a pro in designing large scale distributed systems like YouTube, Netflix, Google Stadia & so on. Zero to Software/Application Architect learning track is a series of four courses that I am writing with an aim to educate you, step by step, on the domain of software architecture & distributed system design. It’s easier, cleaner, secure & provides more control when writing things from scratch as opposed to making it work with third-party code. Users can easily pull out the list of their friends, other relevant information such as games they are playing and stuff.Īll the information which is available to a user on the platform, in general, is also accessible on the chat module. Why Write & Maintain the Chat Feature from Scratch? Why not Integrate a third-party Chat Service?īesides having the generic features, the chat module is integrated with the Fb social graph. The feature is continually improved with the sole aim of providing a top-notch communication service to the users.Ģ. The engineering team of the social platform has scaled it pretty well with response time as less than 100 ms. It facilitates billions of messages sent every single day all across the world. The feature was pretty basic with bare minimum features, the chatbox floated on & could be dragged around the web page, it also persisted through page reloads and other page navigations.Įngineers at Fb took the prototype, evolved it into a full-blown real-time chat feature, one of the most heavily used features in the Facebook services ecosystem. It all started at a hackathon where a few Facebook engineers wrote a chat prototype & presented it before their team.

What technologies does it use on the backend? What is the technology stack? What is the system architecture? What are the primary challenges a platform like Facebook, with such a massive number of users, has to face when rolling out & scaling a feature like this?įor a full list of all the real-world software architecture posts on the blog here you go. In the first, I covered the databases, the persistence tech used this write-up, I will talk about the real-time chat architecture of Facebook which scales with over multi-billion messages sent every single day.
This is my second write-up on Facebook architecture.
