This should prove helpful if you’re looking for which products you’ll need to virtualize your systems, services, applications, and servers:
MS Virtualization SolutionsA comprehensive set of virtualization products, from the data center to desktop assets — both virtual and physical — are managed from a single platformManagement is through System Center
- Profile Virtualization: Document redirection, offline files
- Presentation Virtualization: Terminal Services (through Calista Technologies)
- Desktop Virtualization: Virtual PC (through Kidaro)
- Application Virtualization: Desktop Optimization Pack, Application Virtualization (formerly SoftGrid)
- Server/Desktop Virtualization: Windows Server 2008, Hyper-V Server, Virtual Server 2005 R2, Windows Vista Enterprise, Centralized Desktop
That ought to help.
In the short term, it looks like we must push 2008 as much and as quickly as possible; all of this VM technology will require 2008 Server. Unless, of course, you just want to run some basic 32-bit standalone virtual servers — you can use Virtual Server 2005 R2 for that.
