Developer-side counterpart to CKA. Useful for engineers shipping to k8s, less so for operators.

Who each one is actually for
Certified Kubernetes Administrator
Right fit if
- · DevOps
- · SRE
- · Platform engineers
- · Cloud engineers
Wrong fit if
- · Pure frontend developers
Common misconception
CKA makes you a Kubernetes expert, it proves operator baseline.
CKAD
Right fit if
- · You ship apps onto a cluster regularly
Wrong fit if
- · You manage clusters but don't write services, go CKA
Common misconception
It helps with backend devs adopting k8s. It does not unlock cluster operator roles alone.
Reality check: Scores reflect generalised market signal. The actual weight a cert carries depends on geography, employer tier, and what you've shipped alongside it.
