I was on the reliability team, and we made some of them. One of our sister teams (same Director) was the monitoring team, and they made some features in the monitoring tools that enabled real time export. And then the team that made the deployment tool was also a sister team that made exports easy.
So it was a few teams all reporting to the same Director. We even had the customer service tools reporting to the same director so we could get some real time info from them (and to them).
Each team built in what they were most comfortable. Most of the tools were built in Java, but my team built in Python (mainly because I write in Python and biased towards hiring people who also like to write in Python).
Heh, we're a Java and Python shop to a point, we have done a bit of everything here, but my first project here was to rewrite a legacy Java JSP application and I was given some freedom as to what to rewrite it in, I chose Python and CherryPy. No regrets since.
Sidenote: Other reason I asked is cause apparently both Hulu and Netflix are listed on the CherryPy docs as orgs using them.
