Shared Storage


Failover
Failover

If Node1 fails, the health check will fail, and a failover will happen

Node2 knows what roles Node1 was hosting and the state of those roles through the registry

The application reads its saved data from the shared storage and starts those roles

Client connects to the roles on Node2

Clients may experience an interruption in service during failover
