About a year ago I spent several days trying to get a full puppet system. It was a real headache to be honest and many of the modules have no or very vague docs. Coming back to my setup it's very hard to read or trace what my setup is or how to do one off deployments.

Today I have started with ansible and have already gotten a huge amount done and deployed. Very happy with it. It's all in a small git repo and its very readable and concise.
