It's also worth noting that Windows Server 2008 R2 is ready for VDI. It includes a Connection Broker so that when a user logs in they can be brokered to their appropriate virtual machine or to a remote desktop session. To help with VDI, the company has made a big improvement to the Remote Desktop Protocol (RDP). It offers multi-monitor support, bi-directional audio support, Aero Glass support, and enhanced bitmap acceleration. Microsoft customers have said that they have the bandwidth needed, and would prefer to get the additional performance out of their machines.
Now that Windows Server 2008 R2 has been released, Microsoft is working toward releasing System Center Virtual Machine Manager (SCVMM) 2008 R2 to manufacturing within the next 60 days. The update will improve provisioning of VMs and provide automated storage migration. And it should make Hyper-V a much more solid solution all around.
What do you think? Are these new features and improvements enough to make you switch from your existing hypervisor provider? Are they enough to beat out VMware in a head-to-head sales engagement? If not, what's still missing? Where do they still need to improve?
