Summary
In this chapter, we described how EKS is just a managed version of Kubernetes, with the main difference that AWS will manage and scale the control plane (API servers, etcd) for you, while the cluster users/administrators are responsible for deploying compute and storage resources to host Pods on the cluster.
We also looked at the technical architecture of the AWS-managed control plane and how you can interact with it. However, we pointed out that’s as it is an AWS Managed Service, you have very little ability to modify the servers that make up the control plane.
We then looked at a couple of EKS cost models to help you understand that while the control plane costs are mostly fixed, the costs for compute and storage will vary depending on how many Pods or EC2 worker nodes you have. Finally, we discussed a few common mistakes made by first-time EKS users.
In the next chapter, we will learn how to create an EKS cluster and set up the environment. We will also cover...
