Which means it is my birthday (yay for me!), but it also means that the new Windows Datacenter licensing announced back in July is now in effect. To recap, for those of you who missed the original announcement, Windows Server 2003 R2 Datacenter Edition now has use rights to run unlimited virtualization Windows server instances. Pretty sweet.
