That's what another blogger (or maybe I should say a "real" blogger since I have only been doing this for a month) Mainframe Propeller Head, labels an article in Virtualization Review called Virtual Systems of Tomorrow Could Take Cues from Today’s Mainframes. I couldn't agree more.
This is especially useful for those of you considering investing in the mainframe. It makes the point that the mainframe had virtualization first and that it continues to innovate with virtualization. Kind of an obvious point if you know the mainframe well, but maybe you know about virtualization on another platform and want to get the details on mainframe virtualization and why it could become the x86 virtualization of tomorrow.
