In the quest for centralization, control, ease-of-use, and user enablement, some of the best--and worst--implementations can be qualified by the perceived performance from the users' perspective. There is no greater importance than to deliver the applications to the users that enable them to do what they do--to be as productive and efficient as possible. Not much else matters coming out of the data center. As important as other things are; such as backup, anti-virus, redundancy, disaster planning and recovery; all are for not if the users cannot produce.

VDI is an enabling set of technologies. VDI has been around, in one form or another, since the early 1990s, developed from Terminal Services, Remote Desktop Services, application publishing, and virtual machine hosting. All of these have culminated into a set of well thought-out services that can be implemented and delivered in various ways. Many have witnessed the failure of VDI in their organizations--much of that because of forgotten components and an extremely steep learning curve. Contrarily, there have been outstanding and extremely successful implementations by those who thought of the core components that will make or break the solution, such as storage, profile management, image management, self-service, and simplifying the user experience from end to end. In many instances, indeed, in most instances where VDI is new to an organization, finding the right partner--one who has been around this block before--is critical to an implementation's success.

One thing is clear: Running into a VDI implementation without first considering all of the components is a recipe for disaster. And finding the right partner is key.
