The KCNA Book

By: Nigel Poulton

Overview of this book

There is a huge benefit in building small, specialized, single-purpose apps that can self-heal, auto scale, and update regularly without needing downtime. Kubernetes and cloud-native technologies come in handy in building such apps. Possessing the knowledge and skills to leverage Kubernetes can positively enhance possibilities in favor of architects who specialize in cloud-native microservices applications. ‘The KCNA Book’ is designed to help those working in technology with a passion to become certified in the Kubernetes and Cloud-Native Associate Exam. You will learn about containerization, microservices, and cloud-native architecture. You will learn about Kubernetes fundamentals and container orchestration. The book also sheds light on cloud-native application delivery and observability. It focuses on the KCNA exam domains and competencies, which can be applied to the sample test included in the book. Put your knowledge to the test and enhance your skills with the all-encompassing topic coverage. Upon completion, you will begin your journey to get the best roles, projects, and organizations with this exam-oriented book.

Exam domains and competencies

The overall aim of the KCNA is to test and prove your understanding of the following broad topics:

  • Cloud native and microservices architectures
  • Kubernetes architecture
  • The wider Kubernetes and cloud native landscape (CI/CD, GitOps, observability, security etc.)
  • Basics of using kubectl

The exam tests the following topics that it calls domains and competencies, and you’ll notice they map directly to the chapters of the book. However, the book organises them so each chapter builds on the previous one and prepares you for the next one. As the name of the certification suggests, Kubernetes accounts for nearly half of the exam and the Kubernetes questions feel slightly more in-depth than other topics.
