I agree with this completely but I tend to be in the one VM per app category which puts me solidly in the "one app per box" square. I like what I've heard about Docker because it commercializes and commoditizes the one app per box management philosophy.

I would have said that I'm with Winston Churchill [1] on puppet but I have to say that I'm not. Right now, puppet's what I know. I'm aware of chef and I have seen Ansible in the space. If Ansible is the on that's written in python I think I want to look at that one next.
