Kubernetes in Production Best Practices

By: Aly Saleh, Murat Karslioglu

Overview of this book

Although out-of-the-box solutions can help you to get a cluster up and running quickly, running a Kubernetes cluster that is optimized for production workloads is a challenge, especially for users with basic or intermediate knowledge. With detailed coverage of cloud industry standards and best practices for achieving scalability, availability, operational excellence, and cost optimization, this Kubernetes book is a blueprint for managing applications and services in production. You'll discover the most common way to deploy and operate Kubernetes clusters, which is to use a public cloud-managed service from AWS, Azure, or Google Cloud Platform (GCP). This book explores Amazon Elastic Kubernetes Service (Amazon EKS), the AWS-managed version of Kubernetes, for working through practical exercises. As you get to grips with implementation details specific to AWS and EKS, you'll understand the design concepts, implementation best practices, and configuration applicable to other cloud-managed services. Throughout the book, you’ll also discover standard and cloud-agnostic tools, such as Terraform and Ansible, for provisioning and configuring infrastructure. By the end of this book, you’ll be able to leverage Kubernetes to operate and manage your production environments confidently.

Implementation principles and best practices

In Chapter 1, Introduction to Kubernetes Infrastructure and Production-Readiness, you learned about the 12 infrastructure design principles that we will follow during the book. I would like to start this chapter by highlighting the principles that drove us to this implementation of the cluster infrastructure. The following are the three principles that influenced the implementation decisions in this chapter:

  1. Infrastructure as code: In this chapter, you will write every piece of infrastructure code declaratively. You will achieve this by using Terraform.
  2. Go managed: There are two fundamental ways in which to create a Kubernetes cluster – either to build and operate Kubernetes control plane and workers on your own (on-prem or on cloud), or to use one of the managed Kubernetes services in the cloud, such as Google Kubernetes Engine (GKE), Azure Kubernetes Service (AKS), and AWS Elastic Kubernetes Service (EKS).
