A Kubernetes cluster consists of the components that represent the “control plane” and a set of machines called “nodes”.
The worker nodes host the Pods that are the components of the application workload. The control plane manages the worker nodes and the Pods in the cluster.
(In production environments, the control plane usually runs across multiple computers and a cluster usually runs multiple nodes, providing fault-tolerance and high availability.)
A simple architecture picture is shown as follows:
EKS
As said, EKS is Amazon’s implementation of Kubernetes in the AWS cloud. The difference between EKS and a standard Kubernetes cluster (or what you get as a service in…
