⚖ Autoscaling Servers

[nikhiljha]

Each game and proxy should report a utilization metric (num players connected / player slots). CRDs should define minReplicas (#), maxReplicas (#), and desiredUtilization (%). If the utilization is below the desired utilization, the replicas should be scaled down (with limit as minReplicas). If the utilization is above the desired utilization, the replicas should be scaled up (with limit as maxReplicas).

To determine which games are ready for scale down, there should be a Java API to set canTerminate (bool). If canTerminate is false, the pods should not be terminated. By default, canTerminate is true, so if no plugin sets it, it will be assumed that the server can be stopped. Scaling up is trivial.
