As you certainly know, DevOps is all the rage these days. While DevOps is many things, some pure "buzz" and some legitimate, we aren't going to talk about all that. Instead, let's talk about one small piece of the problem, simplifying the consistency of deployment platforms.

Starting with virtualization, extending to configuration management...
