DevOps is less a job title than a set of habits: automate the release, make the environment reproducible, measure what happens after you ship.
It's the hardest skill here to learn purely from courses, because it only makes sense against a system you're responsible for. Learn the tools, then apply them to something you've built.
What you'll be able to do
- Containerise an application and run it anywhere
- Build a pipeline that tests and deploys on every push
- Debug production instead of fearing it
