Microsoft and Citrix allianced, the program is called "V-Alliance" to offer you the reality of The Optimized Desktop. With Cloud Computing becoming more relevant, it's important to prepare for the next IT evolution. The V-Alliance is shared between Microsoft, Citrix, and Intel. The goal of the alliance is to provide you with a central place to find all the materials you need to address your customers needs for delivering the ultimate desktop.
V-Alliance is rolled out in Europe, is rolling out in the U.S., and will kick-off soon in Asia. Here's a brief video with Citrix's Klaus Oestermann from VMworld Europe 2010.
