While I will admit to being an MVS bigot, it is only fair to mention that IBM also implemented OpenEdition VM; as with MVS, IBM later renamed it.

I have said *many* times that z/OS UNIX nee OS/390 USS nee MVS Open Edition saved the mainframe. Of course, by "mainframe" I meant traditional z/OS mainframe environments. Years ago, I met Bill Schoen at an IBM TDM reception in Poughkeepsie and shook his hand so vigorously that he probably remembers it to this day. I told him that I credited him, more than any other individual in the world, with saving the mainframe. If Don Ault had been there, I would have congratulated him too. That team (I think they were in Kingston at the time) implemented a fundamentally-crucial difference in capability that has been leveraged over the years by TCP/IP, Java, z/OSMF, and many other critical components. And now Kershaw Mehta and his team, standing on the shoulders of giants, continue that great work by fundamentally improving z/OS UNIX to support native containers. -- Phoenix Software International Edward E.
