Overview of this book

The fourth edition of the bestseller Mastering Kubernetes includes the most recent tools and code to enable you to learn the latest features of Kubernetes 1.25. This book contains a thorough exploration of complex concepts and best practices to help you master the skills of designing and deploying large-scale distributed systems on Kubernetes clusters. You’ll learn how to run complex stateless and stateful microservices on Kubernetes, including advanced features such as horizontal pod autoscaling, rolling updates, resource quotas, and persistent storage backends. In addition, you’ll understand how to utilize serverless computing and service meshes. Further, two new chapters have been added. “Governing Kubernetes” covers the problem of policy management, how admission control addresses it, and how policy engines provide a powerful governance solution. “Running Kubernetes in Production” shows you what it takes to run Kubernetes at scale across multiple cloud providers, multiple geographical regions, and multiple clusters, and it also explains how to handle topics such as upgrades, capacity planning, dealing with cloud provider limits/quotas, and cost management. By the end of this Kubernetes book, you’ll have a strong understanding of, and hands-on experience with, a wide range of Kubernetes capabilities.

Cost management

When running Kubernetes at a large scale in the cloud, one of the major concerns is the cost of the infrastructure. Cloud providers offer a variety of infrastructure options and services for your Kubernetes clusters. These are expensive. To harness your costs, make sure you follow best practices such as:

  • Having a cost mindset
  • Cost observability
  • The smart selection of resources
  • Efficient usage of resources
  • Discounts, reserved instances, and spot instances
  • Invest in local environments

This is not necessarily a bad thing, especially for startup companies or new projects. Growth and velocity are often the top priorities. After all, if you don’t have a good product, and you don...
