Yeah, I know. This “Keep Calm” thing has been done to death. I’m only adding to the craziness by associating it with the DevOps movement (although I know I’m not even close to being the first). In this context, CALMS is an acronym coined by John Willis and Damon Edwards and later added to by Jez Humble. CALMS represents five key aspects of DevOps and stands for Culture, Automation, Lean, Measurement, and Sharing.
