DevOps isn't amount making Developers be Ops guys. It's about the fact that automation eats everything, and a significant part of 'ops' is now coding.

A DevOps person isn't someone who develops, and who does Ops. It's someone who does only Ops, but through Development.

It's not about start ups vs Enterprise, it's about 1 person writing programs or 5 people doing things by hand.
