That's not going to happen over night, but that is where things are headed, according to Jocelyn Goldfein, general manager of the Desktop business unit at VMware, speaking in an interview Tuesday.

"Some days I think it's four years away, and other days I think it's all going to happen way faster than we think. I think Microsoft really bobbled with Vista. It's got everyone, including home users, questioning the future of the desktop, and willing to try something new," said Goldfein.

Moving to the cloud will let more companies take advantage of the economies of scale that come with managing many desktops. "People who specialize in desktop management are going to get the best economies of scale of all, and moving the desktop into an external cloud is going to let large or small enterprises, all the way down to SMBs and maybe even home users, take advantage of that," said Goldfein.

Also, most enterprises simply don't want to be in the business of managing desktops, and small to midsize businesses and home users don't want to either. Home users don't want to upgrade operating systems, patch applications or set firewall rules, according to Goldfein.

"The beauty of virtualization, because it decouples the user environment from the device, is that it actually enables someone to deliver that desktop as a service where they can't today," said Goldfein.

An important part of making desktops cloud compatible, and also helping client virtualization go mainstream, is the introduction of so-called "bare metal" hypervisors for client PCs. They allow the desktop to run locally without access to a network and take advantage of the PC's computing power, instead of just relying on the server.

Citrix is working with Intel to develop its CVP (Client Virtualization Platform) for Intel's Intel vPro and Centrino vPro processors, and the result will ship during the second half of the year, VMware announced on Tuesday.

VMware is usually one step a head of the competition in the virtualization space, but not in this case. Citrix already announced plans to come out with a bare metal hypervisor for PCs, and a partnership with Intel, in January. Just like VMware it plans to come out with its product during the second half of 2009.
