// Creates an Amazon EKS control plane. The Amazon EKS control plane consists of
// control plane instances that run the Kubernetes software, such as etcd and the
// API server. The control plane runs in an account managed by Amazon Web Services,
// and the Kubernetes API is exposed by the Amazon EKS API server endpoint. Each
// Amazon EKS cluster control plane is single tenant and unique. It runs on its own
// set of Amazon EC2 instances. The cluster control plane is provisioned across
// multiple Availability Zones and fronted by an Elastic Load Balancing Network
// Load Balancer. Amazon EKS also provisions elastic network interfaces in your VPC
// subnets to provide connectivity from the control plane instances to the nodes
// (for example, to support kubectl exec, logs, and proxy data flows). Amazon EKS
// nodes run in your Amazon Web Services account and connect to your cluster's
// control plane over the Kubernetes API server endpoint and a certificate file
// that is created for your cluster. In most cases, it takes several minutes to
// create a cluster. After you create an Amazon EKS cluster, you must configure
// your Kubernetes tooling to communicate with the API server and launch nodes into
// your cluster. For more information, see Managing Cluster Authentication
// (https://docs.aws.amazon.com/eks/latest/userguide/managing-auth.html) and
// Launching Amazon EKS nodes
// (https://docs.aws.amazon.com/eks/latest/userguide/launch-workers.html) in the
// Amazon EKS User Guide.
