Before containers, I had sysadmins who ran our AIX cluster. Three nodes, not a single one configured like the other. There was zero consistency where it counted and these jokers would go on a terminal and manually configure Websphere and other components and screw it up constantly. We even tried to give them a terminal tool where you could type in one window and it would mirror on other boxes, but they refused to use it. Puppet, Chef, Ansible, all led the way to something better. Docker and Kubernetes feel so far advanced from what we had in 2012.
