Really the only certs that matter are those from Cloud Native Foundation:
I have heard people say CKA is harder and should be first, and vice versa. I’m getting CKAD because I lean toward applications development more than operations and administration. (I’m about 70% dev and 30% admin.)
I’m getting it because Kubernetes has many disparate parts and I want to be sure I’ve covered everything with no gaps. The CNCF certs are also done through interactive challenges instead of multiple choice. I also want to be able to help others who want to go through the process, even though not everyone might actually need to go through it.
Keep in mind, getting the certification is only the beginning of what you will need to actually get a job doing it. I personally believe you should regularly run and maintain a local Kubernetes cluster on hardware in your home lab before really seeking employment.
