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.

Serverless Computing on Kubernetes

In this chapter, we will explore the fascinating world of serverless computing in the cloud. The term “serverless” is getting a lot of attention, but it is a misnomer. A true serverless application runs as a web application in a user’s browser or a mobile app and only interacts with external services. However, the types of serverless systems we build on Kubernetes are different. We will explain exactly what serverless means on Kubernetes and how it relates to other serverless solutions. We will cover serverless cloud solutions, introduce Knative - the Kubernetes foundation for functions as a service - and dive into Kubernetes Function-as-a-Service (FaaS) frameworks.

This chapter will cover the following main topics:

  • Understanding serverless computing
  • Serverless Kubernetes in the cloud
  • Knative
  • Kubernetes FaaS Frameworks

Let’s start by clarifying what serverless is all about.
