Scaling Signaling with Rooms and Redis
Learn to scale a WebRTC signaling server horizontally using room-based message routing and a Redis pub/sub adapter so peers on different server instances can still connect.
One Server Is Not Enough
You have built, deployed, and tested a signaling server. As users grow, a single instance becomes a bottleneck. This lesson covers scaling signaling horizontally across multiple instances using rooms and Redis.
The Room Concept
Signaling messages should only reach the right peers. A room groups the participants of one call so offers, answers, and ICE candidates are routed only to members of that room.
