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.

What is AWS Fargate?

AWS Fargate was developed as an alternative to EC2 to provide a serverless, container-native compute solution with three key design tenets:

  • To be as secure as possible
  • To be reliable and scale to meet demand
  • To be cost-efficient

If we compare the EC2-based EKS worker node and Fargate technical stacks, illustrated in Figure 15.1, we can see that they are very similar. They run on physical servers, with both a virtual machine operating system and a container runtime that support a containerized application. The key difference is that Fargate is serverless, which means that you don’t need to care about the virtual machine operating system, container runtime, and so on, as this is all managed by AWS:

The other main difference is that Fargate is really designed for small, bursty, or batch workloads, unlike EC2, which is traditionally used for more stable, long-running...
