The container orchestration certifications for cloud-native engineering
CNCF (Cloud Native Computing Foundation) certifications validate Kubernetes expertise — the de facto standard for container orchestration. Unlike most certs, CNCF exams are performance-based (hands-on terminal, no multiple choice) and the most practical certifications in cloud-native engineering. All are valid for 2 years.
New to Kubernetes
KCNA for concepts, then CKA for hands-on cluster administration — the most in-demand cert.
Developer deploying to K8s
CKAD — it focuses on application deployment, not cluster admin.
CKA already certified
CKS — validates security hardening skills and is required for many security-adjacent K8s roles.
Conceptual — suitable as a starting point
Hands-on terminal exams — lab environment, no multiple choice
Are CKA exams really hands-on?
Yes — all CNCF professional exams are conducted in a live terminal environment. No multiple choice. You solve real cluster problems in 2 hours. This makes them highly respected by employers.
Do I need CKA before CKS?
Yes — CKS formally requires an active CKA certification. You must hold CKA before registering for CKS.
