Overview of this book

Kubernetes has been widely adopted across public clouds and on-premise data centers. As we're living in an era of microservices, knowing how to use and manage Kubernetes is an essential skill for everyone in the IT industry. This book is a guide to everything you need to know about Kubernetes—from simply deploying a container to administrating Kubernetes clusters wisely. You'll learn about DevOps fundamentals, as well as deploying a monolithic application as microservices and using Kubernetes to orchestrate them. You will then gain an insight into the Kubernetes network, extensions, authentication and authorization. With the DevOps spirit in mind, you'll learn how to allocate resources to your application and prepare to scale them efficiently. Knowing the status and activity of the application and clusters is crucial, so we’ll learn about monitoring and logging in Kubernetes. Having an improved ability to observe your services means that you will be able to build a continuous delivery pipeline with confidence. At the end of the book, you'll learn how to run managed Kubernetes services on three top cloud providers: Google Cloud Platform, Amazon Web Services, and Microsoft Azure.

Introduction to DevOps

Over the past few years, the software delivery cycle has been moving increasingly fast, while at the same time application deployment has become more and more complicated. This increases the workload of all roles involved in the release cycle, including software developers, Quality Assurance (QA) teams, and IT operators. In order to deal with rapidly-changing software systems, a new concept called DevOps was introduced in 2009, which is dedicated to helping the whole software delivery pipeline evolve in order to make it faster and more robust.

This chapter covers the following topics:

  • How has the software delivery methodology changed?
  • What is a microservices architecture? Why do people choose to adopt this architecture?
  • What is DevOps? How can it make software systems more resilient?
