Getting started

Kubernetes and cloud native technologies are all the rage and are shaping the world we work in. Building apps as small, specialised, single-purpose services that can self-heal, autoscale, and be regularly updated without downtime brings huge benefits. However, possessing the knowledge and skills to leverage these technologies is a huge career boost for you as an individual. For example, knowing how to design, build, and troubleshoot cloud native microservices applications running on Kubernetes can get you the best roles, on the best projects, at the best organisations. It can even earn you more money.

With all of this in mind, the Cloud Native Computing Foundation (CNCF) designed the KCNA exam and certification as a way for you to prove your competence with these technologies.

This book covers all of the exam objectives in one place in a well-organised and concise format. It’s useful as both a revision guide and a place to start learning new technologies and concepts. For example, if you already know the basics of Kubernetes, the book will reinforce everything you already know, as well as test your knowledge with its extensive quizzes and explanations. However, if you’re new to any of the topics on the exam, the book will get you up-to-speed quickly.
