There's a lot of talk about what is or what is not DevOps, and I'll throw my opinion in the mix.
Until a few weeks ago, at work, we had mostly two teams: the engineering team and the ops team. Our workflow was (to simplify) the following:
There's already a lot of articles about the kind of frictions created by this (who owns what; engineers would blame ops when the push was failing (or the other way around); it's hard for ops to know what's wrong when something is broken in production; etc).
A few weeks ago it was decided to create a new team to improve engineers efficiency, and the team was named "DevOps". At first I was not sure it was the right name for this team, but now I don't think it matters.
I was not sure the name was appropriate because of this article (and a few other to respond), explaining why you don't want a DevOps team, but instead you want the whole organization to be DevOps. We need engineers to own their applications, to be able to push when they want, but also to monitor, know what's wrong or slow, etc.
The work hachi and I will have to do is to help engineers and ops to be the DevOps. Our team responsibility is to choose, evaluate and integrate tools. We will also provide libraries, documentation, training and support. We are not the DevOps. Our goals are to create this culture, to give more responsibilities to engineers, and to free Ops from the work of pushing code. The success of this team will be measured by the adoption of our work by engineers and ops.
So yes, I agree that you don't want a dedicated DevOps team, but you still need a team coming from different background (hachi is coming from Ops and I'm an engineer) to build that culture.
