Who this book is for

This book is written for professionals who are new to OpenShift, but it also covers some advanced topics as well, such as CI/CD pipelines, high availability, and multi-data center setups. Readers do not require any background in Docker, Kubernetes, or OpenShift, although familiarity with the basic concepts will be beneficial. The book doesn't cover how to work with Linux though, so at least a year of previous experience with Linux is expected. The primary goal of this book is not so much about theoretical knowledge, as it is about hands-on experience, which is why we use a practical approach with virtual labs where possible. The book starts by introducing readers to the concept and benefits of containers in general, in order to get newcomers up to speed quickly, and then builds on that foundation to guide readers through the basic and advanced concepts of Kubernetes and OpenShift. The book finishes by providing readers with an architectural reference for a highly available multi-data center setup. Before we started working on this book, we realized that there is very little information available on how to deploy OpenShift in multiple data centers for high availability and fault tolerance. Due in no small part to that, we decided to pool our experience and collaborate on writing this book.
