Be able to start a video conference within the same private chat.
Horizontally scaled the two instances of app server using Load Balancer and Redis Adapter.

Technology Stack

Backend: NodeJS + Express
VueJS as frontend framework
Redis as a database in memory
Docker & Docker Compose

Application Architecture

As we are running two diferrent instances of app server, with each server maintaining the data of it's own users locally so in case if two users want to communicate with each other but they are connected with different instances then it's not going to happen. So we need a shared memory which is accessible by both app servers and here come's the Redis into picture.

In case of Docker, we'll be running 3 containers the first two for app servers and third one for Redis.

Interested in knowing how Video Communication works?

I'm using WebRTC is a free and open project that provides web and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. WebRTC enables peer to peer communications even tough it still needs a server for the signaling process. In this case the private chat rooms will be used as the signaling mechanism between the two users
