I’ve been talking to a lot of people about DevOps, and started become frustrated that there was so little definition about what DevOps means, even at a high level – and especially the role that Operations plays in the overall DevOps picture. So I did what I usually do when confronted with that kind of a problem: I wrote a book. It’s free, it’s online now, and it’s something I’ll continue to add to, evolve, and revise over time.
