Chapter 1. Introduction
Kubernetes is an open source orchestrator for deploying containerized applications. It was originally developed by Google, inspired by a decade of experience deploying scalable, reliable systems in containers via application-oriented APIs.1
Since its introduction in 2014, Kubernetes has grown to be one of the largest and most popular open source projects in the world. It has become the standard API for building cloud native applications, present in nearly every public cloud. Kubernetes is a proven infrastructure for distributed systems that is suitable for cloud native developers of all scales, from a cluster of Raspberry Pi computers to a datacenter full of the latest machines. It provides the software necessary to successfully build and deploy reliable, scalable distributed systems.
You may be wondering what we mean when we say “reliable, scalable distributed systems.” More and more services are delivered over the network via APIs. These APIs are often delivered by a distributed system, the various pieces that implement the API running on different machines, connected via the network and coordinating their actions via network communication. Because we increasingly rely on these APIs for all aspects of our daily lives (e.g., finding directions to the nearest hospital), these systems must be highly reliable. They cannot fail, even if a part of the system crashes or otherwise stops working. Likewise, they must maintain availability even during software rollouts ...
