Virtualization of IBM® z/OS® on Intel

Why would you need an IBM Mainframe? For running mainframe applications? Not really.

Interesting question. I had completely forgotten about the endeavor Amdahl had embarked on until a highly respected colleague (thanks, Cameron) pointed me to that company again: PSI, providing virtual machines for most mainframe operating systems.

But be aware of the caveat: Nobody would allow his crown jewels being “taken”. IBM sued PSI, PSI counter-sued IBM, and the story will continue. And why should that be important at all? Check the stake holders – we’re talking about big money.
