They have comprehensive courses about nearly every DevOps topic and are still adding new stuff. I like the Cloud Playgrounds section most and the career path approach is amazing. In that way, even if you are unfamiliar with the DevOps stuff, you are getting the right base courses and building your knowledge on top of it later. After learning each topic the platform provides you with a topic-specific lab with many tasks so while you are solving them you are making practice of the theory as well. I use the KodeKloud & KodeKloud Engineer platform every day.

Several courses over multiple IT domains. Everything from essentials to expert level courses. Highly recommend. Includes labs, playgrounds, sandboxes and structured learning.

You can practice what you just have learned. The labs are awesome.
