Node Groups

EC2 node groups that provide compute capacity for your EKS cluster.

Node Groups are managed groups of EC2 instances that provide compute capacity for the EKS cluster. Each node group defines the instance type, scaling configuration, and optional taints or labels applied to its nodes.

If your Cluster Baseline uses EKS Auto Mode, AWS manages compute capacity automatically and node groups are not required.
