Amazon Elastic Kubernetes Service now permits tuning parameters of Kubernetes control plane components such as scheduler, controller manager, and API server. These configurations allow customized pod placement strategies, event retention settings, and autoscaling responsiveness, enhancing resource efficiency and workload performance.
For example, administrators can switch the scheduler's node fit strategy from spreading pods (LeastAllocated) to packing them densely (MostAllocated), potentially reducing node usage. This flexibility helps adapt cluster behavior to specific workload priorities and is available in all AWS Regions supporting EKS.
