OpenShift 4.21 introduces two new resource management features for hosted control planes (HCP): dynamic control plane scaling and autoscaling from/to zero for node pools. Dynamic scaling uses a Vertical Pod Autoscaler (VPA) to monitor kube-apiserver memory usage and automatically right-size control planes based on actual load rather than node count. Scale-to-zero allows node pools (including expensive GPU pools) to fully terminate when idle and provision on demand when workloads arrive. Both features are initially available on Red Hat OpenShift Service on AWS with HCP, with plans to extend to Azure and on-premises. Together they eliminate idle resource costs while maintaining SLAs and reducing operational toil for SREs.
