Microsoft just released an introductory book about its virtualization products for free:
|Understanding Microsoft Virtualization Solutions (From the Desktop to the Datacenter)
Mitch Tulloch (with the Microsoft Virtualization Team)
The book covers Hyper-V 2008, System Center Virtual Machine Manager (SCVMM) 2008, App-V (formerly Softricity SoftGrid), Terminal Services, MED-V (formerly Kidaro Managed Workspace), Microsoft Assessment & Planning Toolkit and even the technologies that Microsoft is trying to market as profile virtualization: User Profiles, Folder Redirection and Offline Files.
Some chapters are very basic (for example the one about MED-V) while others are pretty detailed (like the ones about Hyper-V and SCVMM).
Overall, this book is without doubts the best overview available today to understand the Microsoft virtualization offering.
If you are evaluating the adoption of one of the products above it deserves a read.
Thanks to Andrew Dugdell for the news.
