I cut my teeth on mainframe computers. My first system administration language wasn’t — as you might guess from my Unix/Linux background — Borrne or C shell, but rather, IBM 360 mainframe Job Control Language (JCL). So, the notion that a DevOps system, such as Red Hat Ansible, could ever control a mainframe is a little mind-blowing. Sure, IBM mainframes have been using Linux for 20 years now, but DevOps on a mainframe? Really?
