Overview of this book

Kubernetes has emerged as the de facto standard for container orchestration, with recent developments making it easy to deploy and handle a Kubernetes cluster. However, a few challenges such as networking, load balancing, monitoring, and security remain. To address these issues, Amazon EKS offers a managed Kubernetes service to improve the performance, scalability, reliability, and availability of AWS infrastructure and integrate with AWS networking and security services with ease. You’ll begin by exploring the fundamentals of Docker, Kubernetes, Amazon EKS, and its architecture along with different ways to set up EKS. Next, you’ll find out how to manage Amazon EKS, encompassing security, cluster authentication, networking, and cluster version upgrades. As you advance, you’ll discover best practices and learn to deploy applications on Amazon EKS through different use cases, including pushing images to ECR and setting up storage and load balancing. With the help of several actionable practices and scenarios, you’ll gain the know-how to resolve scaling and monitoring issues. Finally, you will overcome the challenges in EKS by developing the right skill set to troubleshoot common issues with the right logic. By the end of this Kubernetes book, you’ll be able to effectively manage your own Kubernetes clusters and other components on AWS.

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...
