This is a story of a flawed development process on top of a flawed infrastructure, without the necessary data to drive decision-making. It’s also a story of waking up to these problems and charting a way out.
As it turns out, pure reasoning cannot solve the kind of problems you see in the production environment of a complex application. These problems are almost always more difficult, since they have survived all of the testing you could throw at them.
A story of a somewhat rare failure case (a datacenter heat buildup event) and how to monitor for such a thing without contributing to metrics overload.
