EKS

And take your prize!

Amazon Elastic Kubernetes Service (Amazon EKS) - a managed service that you can use to run Kubernetes on AWS without needing to install, operate, and maintain your own Kubernetes control plane or nodes.

AWS EKS Setup

Amazon Virtual Private Cloud (Amazon VPC) is a service that lets you launch AWS resources in a logically isolated virtual network that you define.

Setup

AWS CLI version 2 installation instructions:
