Athletes, Firemen and Doctors train everyday to be the best at their chosen profession. As engineers, we spend much of our time getting stuff to production and making sure our infrastructure doesn’t burn down out right. In this talk, we'll discuss the need for and the options of creating a game day culture. Where we as engineers not only write, maintain and operate our software platforms but actively pursue ways to learn and predict its (non-functional) behavior. We'll look at tools like toxiproxy and the simian army for ways to prepare teams to tweak their testing and monitoring setup and work instructions to quickly observe, react to and resolve problems.
