These are the three key components of a desktop and if you
can abstract these layers from one another, then you can significantly reduce desktop management overhead. This is where desktop virtualization products can help. Because the desktop is contained within a virtual machine, you gain all of the advantages and few of the issues that come with machine management when a machine is transformed from the phys- ical to the virtual. You also greatly simplify how systems must be constructed and deployed, especially if you rely on centralized desktop virtualization.
