Architecture for
Room A
Frontend instanceRoom B
Relatively small instances to serve a few roomsRelatively small MCUs to serve a few roomsMemcache and/or REDIS to reduce DB pressure
15
Why small instances in
+ Allow to cache many DB requests (for example room content, participants, history, …)+ If a small instance or MCU fail casualties are minimal (a few rooms)
+ No need for complex configuration- difficult to monitor
+ Fast recovery and traffic spikes adaptation
- difficult to adapt for very dynamic rooms
