I attended the CALUG (Columbia Area Linux User Group) meeting tonight. The presentation was on IBM z/OS and virtual Linux machines.
It was a good presentation! A clear overview and lots of technical details. More impressive than the presentation was the set of questions asked by members of the audience. They knew their stuff, from old IBM mainframe concepts (partitions, microcode, and DASD) to the new concepts (virtual machines, Linux instances, and databases). OK, perhaps the concept of a virtual machine is not that new. But the audience was interested and inquisitive.
I left with a lot of information about z/OS and Linux. IBM has made some good choices with its technologies, and I think they are well-positioned to leverage their tech for cloud apps.
