Start here
Cloud and DevOps certifications test what you can do in a terminal. Practise exactly that, on real infrastructure, from your first lesson to your last mock exam.

Why certify
A certification is not the goal. The skills behind a hands-on one are, and the exam is a good, honest test of them.
The CKA, CKAD and CKS hand you a cluster and a problem. Passing means you fixed things in a terminal against the clock, not that you recognised answers.
Each exam publishes its domains and weights. That gives you a clear map of what to learn, and gives a team a common bar for everyone.
Administrator first, then developer or security, then the cloud and infrastructure-as-code exams. Each builds on skills from the one before.
Where to begin
It is ready today: the CKA course (17 modules, 38.5 hours), 134 labs with 305 graded tasks, and 15 timed mock exams. The other paths build on it.
