KCNA — Introduction
Chapter Overview
The Kubernetes and Cloud Native Associate (KCNA) is the most beginner-friendly certification from the Cloud Native Computing Foundation (CNCF). It validates your foundational understanding of Kubernetes and the cloud-native ecosystem — containers, orchestration, architecture, observability, and application delivery.
Think of KCNA as the gateway certification for cloud native. While CKA tests whether you can manage a cluster and CKS tests whether you can secure one, KCNA tests whether you understand the concepts that make these technologies work. It’s pure theory — no terminal, no live clusters, just multiple-choice questions.
If you’re starting your cloud-native journey, considering a role in DevOps, or simply want to formalize what you know about Kubernetes, the KCNA is the perfect starting point.
