Scale Kubernetes clusters to 2,500 nodes — control plane and network implications

AI Impact Summary

Scaling Kubernetes to 2,500 nodes enables larger production workloads but puts the control plane under heavy load. API latency and etcd performance become critical as the cluster grows, so ensure kube-apiserver, etcd, and scheduler are appropriately sized and load balanced. Autoscaler behavior, network plugins, and DNS must be validated for stability at this scale. This requires an operational readiness plan and potential architectural adjustments before production rollout.
