We use golang for a lot of our ops stuff. Earlier it was a repo of a mash of different python/ruby scripts. The runtime dependencies were hard to keep track of and they had to be installed on all the machines depending on the script being run.

With golang it's just one static binary that is scp'ed across the nodes. This easy of deployment isn't talked about much.

We were also able to go further and put a RESTFUL API on top of these tools using negroni and gorillamux.
