Hi, I’m David Greschler, Director of Microsoft virtualization and management. Today VMware announced their new “Cloud OS,” called vSphere. It’s an interesting announcement in that it points out more clearly than ever that VMware adds an extra layer to the computing stack. This extra layer, a virtualization “substrate” (VMware CEO Paul Maritz’s words), is inserted by VMware between hardware and the OS. But is it really necessary to add an extra layer just to do virtualization and the cloud? Do we really need another operating system to effectively just host other operating systems? I can see how initially this made sense when the industry was first experimenting with virtualization. But virtualization has now become mainstream, and as such it’s just another feature we should have as part of our computing process. As a result, Microsoft chose to take a more streamlined approach to virtualization. Instead of adding an additional layer of complexity, we’ve put the virtualization component inside the OS. We think this is a better approach as it means you have one less layer to manage, secure and pay for.
