That, he said, becomes a much more complex task. With tactical virtualization, data center architecture doesn't change completely. But there are more moving parts that have to work together with a strategic virtualization approach.
From Kerravala's perspective, it's incumbent upon vendors to help IT departments understand how these pieces are all tied together. VMware's move to open up its certification program allows the company to branch into broader pre-configured, pre-tested solutions that give customers confidence to use virtualization for much more than they have in the past. That, of course, directly benefits VMware.
"This whole market is becoming a game of stacks. If you look at the VCE Alliance and Oracle's Exadata stack and what VMware is trying to do on its own, we are moving back to an era of pre-integrated, pre-configured solutions just like the mainframe market was. It just happens to be built on open systems," Kerravala said. "So the vendors to offer complete solutions to their customers better and faster will wind up being the long-term winners."
