What I find so funny about this is that people are now doing with containers what people have been doing with mainframes for decades. That is, running thousands of virtualized environments on a typical server.<p>I remember logging into a 3270 terminal to a screen displayed by VMS (the virtualization manager) which would immediately spin up a virtual machine running your own copy of CMS for you do development or other command line work.<p>It is so much fun to see things go full circle.
