| Kubernetes Control Plane tier | Limit |
|---|---|
| Standard tier | Automatically scales Kubernetes API server based on load. Larger control plane component limits and API server/etcd instances. |
| Free tier | Limited resources with inflight requests limit of 50 mutating and 100 read-only calls. Recommended node limit of 10 nodes per cluster. Best for experimenting, learning, and simple testing. Not advised for production/critical workloads. |
