DevOps Certifications Roadmap
So, when we talk about DevOps certifications, it is more certifications that are related to DevOps practice. It could be a certification based on the tool, cloud platform, SCRUM, etc.
My first certification as a Devops engineer was AWS-certified solution architect because I was primarily working on AWS cloud-related projects. It makes more sense to start with a certification on the technologies you are working with.
For example, if you are a Linux admin and want to become a DevOps engineer, you can get certified in Kubernetes as it is more relevant to the domain you are already in. That is “System Administration”.
Here is my advice on devops certification.
Start with one Certification that is closely related to your existing domain. If you are completely new to DevOps, the following DevOps certification roadmap would help.
