Kevin Lees has just posted a great article on the Virtual Strategy magazine pages, called PMP'n Virtualization – Part One
I really like the way he put most of the advantages of adopting virtualization technologies in just a fwe paragraphs, and happen to agree that such a complex set of technologies brings not only benefits, but also risks, and definitely needs a structured approach to its implementation.
Here's just a few lines from the original article, please read it in full if you're interested:
Desktop virtualization changes the way IT provides the desktop infrastructure. In addition to making the low cost, thin client desktop a tenable solution, hosting the “PC” in datacenter-resident virtual machines fundamentally changes how desktops are managed by IT.
Virtualization, specifically the speed with which virtual machines can be created and deployed, supports a faster IT response to changing business needs. The cycle time from business need recognition to business solution implementation by IT will continue to shrink as IT standardizes on virtual machine usage.
