I do enjoy seeing all the work going into building out and solving the very real problems associated with running software in distributed systems. DevOps has embraced a lot of this work. I think this is a short term engagement. At its core, DevOps is about empowering developers to deploy and to watch their own applications in production. In the not too distant future, I see distributed systems design returning to its natural home as a part of operating systems design. And DevOps as a category will fade away and we will again focus on application design in a much richer systems environment.
