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.

Community and governance

Most cloud native technologies, including Kubernetes, are open source. This gives them access to large and passionate communities that develop and support them. However, strong governance is required to provide direction and order.

To address this requirement, the Cloud Native Computing Foundation (CNCF) was founded in 2015. It defines three maturity stages projects have to pass through on their journey to “graduation”. The stages are.

  1. Sandbox
  2. Incubating
  3. Graduated

This three-step process helps projects mature and eventually graduate as production-grade projects that can thrive and bring value to the community. Kubernetes was the first CNCF project and graduated in 2018. Since then, more than 15 other projects have graduated, and more than 100 are either in the sandbox or incubating stages.

Projects have to prove their maturity to the CNCF Technical Oversight Committee (TOC) if they want to progress through the stages. Each stage has...
