 ## Cilium Components
 
 The primary Cilium Agent runs as a DaemonSet on each Kubernetes node.  Each cluster also includes a Cilium Operator Deployment to handle certain cluster-wide operations.  For EKS Anywhere, Cilium is configured to use the Kubernetes API server as the identity store, so no etcd cluster connectivity is required.
