HA-RealtimeGame

A basic game made with constraints for distributed systems's course at ESIR :

• Realtime client-server multiplayer
• High Availability (SPOF elimination, redundancy, automatic failure detection & mitigation)
• Basic graphical interface

One-click demonstration :

1. Wait for servers to start and page being displayed
2. Navigate to the left side "Docker" section
3. Stop the currently used container (deno-1, port 8080)
4. Observe that websockets automatically migrate to other replicas and the game still works !
