A cluster can contain several node groups. Each node group contains one or more nodes that are deployed in an link:autoscaling/ec2/userguide/AutoScalingGroup.html[Amazon EC2 Auto Scaling group,type="documentation"]. The instance type of the nodes within the group can vary, such as when using link:AWSEC2/latest/UserGuide/ec2-fleet-attribute-based-instance-type-selection.html[attribute-based instance type selection,type="documentation"] with https://karpenter.sh/[Karpenter]. All instances in a node group must use the <<create-node-role,Amazon EKS node IAM role>>.

Amazon EKS provides specialized Amazon Machine Images (AMIs) that are called Amazon EKS optimized AMIs. The AMIs are configured to work with Amazon EKS. Their components include `containerd`, `kubelet`, and the {aws} IAM Authenticator. The AMIs also contain a specialized https://github.com/awslabs/amazon-eks-ami/blob/main/templates/al2/runtime/bootstrap.sh[bootstrap script] that allows it to discover and connect to your cluster's control plane automatically.
Amazon EKS provides specialized Amazon Machine Images (AMIs) that are called Amazon EKS optimized AMIs. The AMIs are configured to work with Amazon EKS. Their components include `containerd`, `kubelet`, and the {aws} IAM Authenticator. The AMIs use https://awslabs.github.io/amazon-eks-ami/nodeadm[nodeadm], a tool that automatically connects nodes to your cluster's control plane and configures `kubelet` and `containerd`.

If you restrict access to the public endpoint of your cluster using CIDR blocks, we recommend that you also enable private endpoint access. This is so that nodes can communicate with the cluster. Without the private endpoint enabled, the CIDR blocks that you specify for public access must include the egress sources from your VPC. For more information, see <<cluster-endpoint>>.
