"Virtualization is a how, not a what," says Jerry Chen, VMware's senior director, enterprise desktop. The truth of this statement -- and the extent to which some people in the virtualization community forget this truth- struck me Tuesday, after I got an update from Chen on VMware's strategy and plans for desktop PC virtualization.
For the most successful IT teams, virtualization is a how. It's how you cut datacenter costs; it's how you provision new PCs faster to the business than ever before; it's how you get to say "yes" to many business-side requests that used to take months and thus used to require a "no." Desktop virtualization could be the how to another classic IT problem: Desktop PCs still take much too much time and money to manage.
The security and management-related benefits of desktop virtualization are easy to understand for industries like financial services and healthcare, which, not surprisingly, are two of the markets where VMware is having early success. (Government and education are also buying into the idea, Chen says.) Retail companies with many branch offices, knowledge firms like law firms, and even some manufacturing companies are starting to be verticals where VMware is selling desktop virtualization more, Chen says.
Still, when you consider the three main types of virtualization, server, storage, and desktop, desktop lags in adoption behind the other three, to date. In CIO's latest survey of enterprise IT leaders on virtualization, 25 percent of you said you are currently using virtual desktops; 13 percent plan to do so within a year, and 21 percent plan to do so within one to three years. But 37 percent of respondents have no plans to use virtualized desktops.
Sure, you've been stung by previous technology vendor promises to simplify PC management. It would be hard to find an IT leader who hasn't been; it's just a matter of how badly you've been stung. VMware faces this legacy.
But two desktop virtualization technology improvements, currently in the works and demonstrated at the recent VMworld show in Cannes, could make desktop virtualization a much more appetizing proposition for enterprise IT.
The first is what VMware calls "offline VDI" (virtual desktop infrastructure), and it means new flexibility for users of VMware's desktop virtualization technology. Users will be able to work offline then check back in with the server and stream changes back to the VM. On the management side, IT will be able to manage desktop and laptop users in a more similar way, Chen notes.
The second improvement, scalable virtual images, is a technique that VMware believes will reduce management overhead and storage costs, for all those VMs for users. Desktop virtualization users will have a "master" virtual machine with "child" VMs that store only the differences in that individual user's VM as compared to the master. This means much less storage space is required per user. It also means when you roll out a new app or patch, you just update the master.

Server virtualization is a popular option for dealing with mounting datacenter costs. Another equally promising approach is the use of an Application Delivery Controller. Citrix NetScaler provides a low-cost way for organizations to reduce their server count and accrue cost savings from a reduction in space, cooling, power and personnel.
