Next Level: DevOps

Gave this talk at EnterJS in Cologne, Germany on July 1st, 2014
Follow me on Twitter: @CodeStars

My current company hired me as a Software Engineer. Their software has organically grown over the past six years and it really looks like what you would expect, when you hear that a software system is that old. There was no real abstraction, no idea of services - nothing fancy.
I realized that if I wanted to change the software I had to start with the system architecture. Thus, I joined the infrastructure team where I learned a lot of new stuff as well as what it meant to be on call.
