In this chapter, we discussed the public cloud. AWS is the most popular public cloud service and it gives APIs the ability to control AWS infrastructure programmatically.

In addition, AWS EKS makes it easy to deploy Kubernetes on AWS. Furthermore, the control plane manages the master and etcd with high availability design that offloads huge management efforts.

On the other hand, you need to be aware of AWS basics such as availability zone awareness between pod (EC2) and persistent volume (EBS). In addition, you need intermediate AWS knowledge such as IAM credentials to gain access to an API server and use a worker node Instance Role ARN to register the cluster.

In addition, using ALB as ingress controller is available as of December 2018 (https://aws.amazon.com/blogs/opensource/kubernetes-ingress-aws-alb-ingress-controller/), but it also requires additional effort to configure this.

Although AWS keeps improving functionality, open source tools such as eksctl indicate EKS still requires more improvement for easier use of Kubernetes.

In Chapter 11, Kubernetes on GCP, we'll introduce Google Cloud Platform and Kubernetes Engine, which is a pioneer for making a hosted Kubernetes service on Cloud. This is more mature than AWS EKS.
