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.

Understanding AWS App Mesh

There are many different service mesh implementations. We will focus on AWS App Mesh as it is a fully managed service, but bear in mind other meshes such as Istio, Linkerd, and Gloo are available (take a look at https://layer5.io/service-mesh-landscape if you want a community view). AWS App Mesh provides consistent network controls across Amazon EKS, AWS Fargate, Amazon ECS, Amazon EC2, and Kubernetes on EC2 using a sidecar data plane based on the Envoy proxy. We will focus on the EKS usage but bear in mind one of the major reasons for using AWS App Mesh is its ability to provide traffic control and visibility across applications deployed across a variety of different compute services in AWS.

AWS App Mesh implements a number of different constructs to control and monitor application traffic. The main one is the mesh itself. You can have multiple meshes in an account and each represents a logical network boundary for all the applications/services to reside...
