Guides
DevOps guides.
Long-form, worked-through explanations rather than reference pages — 8 of them, roughly 12 hours of reading. Each one goes deep enough that you finish able to debug the thing, not just name it.
If you are not sure where to start, the DevOps roadmap sequences these in the order they build on each other.
