Cloud Native DevOps with Kubernetes, 2nd Edition

Chapter 1. Revolution in the Cloud

There was never a time when the world began, because it goes round and round like a circle, and there is no place on a circle where it begins.

Alan Watts

There’s a revolution going on. Actually, three revolutions.

The first revolution is the creation of the cloud, and we’ll explain what that is and why it’s important. The second is the dawn of DevOps, and you’ll find out what that involves and how it’s changing operations. The third revolution is the wide adoption of containers. Together, these three waves of change are creating a new software world: the cloud native world. The operating system for this world is called Kubernetes.

In this chapter, we’ll briefly recount the history and significance of these revolutions, and explore how the changes are affecting the way we all deploy and operate software. We’ll outline what cloud native means, and what changes you can expect to see in this new world if you work in software development, operations, deployment, engineering, networking, or security.

Thanks to the effects of these interlinked revolutions, we think the future of computing lies in cloud-based, containerized, distributed systems, dynamically managed by automation, on the Kubernetes platform (or something very like it). The art of developing and running these applications—cloud native DevOps—is what we’ll explore in the rest of this book.
