AWS Elastic Kubernetes Service (EKS) is a managed Kubernetes solution for running containers available in AWS cloud platform since June 2018 [1]. EKS can be managed using Jenkins X software [2]. Other AWS services for running containers are ECS or Fargate.

By default EKS provides 3 master nodes and 3 etcd nodes, but are invisible to you and Amazon is responsible of AutoScaling them when needed.
