What Virtualization Technology is being used for Azure VMs

Question

I would like to know what virtualization technology is being used for VMs running in Windows Azure. I am specifically looking for what type of hypervisor is being used. Such as Microsoft Hyper V, Xenserver, Vmware ect.

Thanks.

Answer 1

There's no real details on it, but essentially its a highly customized version of hyper-v that is not available publically.

Answer 2

Thanks for the response. I figured it was some version of Hyper V but wanted confirmation.

Answer 3

Virtualization Layer is pretty much Hyper-V, but the management layer (Fabric Controller) is highly customized. This allows to migrate VM seamlessly between Cloud (Azure) and on-premise, Hyper-V based hosting, in both directions.

MSFT also released a CTP enabling Hosting Providers similar VM hosting experience as the Azure Infrastructure as a Service: http://www.microsoft.com/hosting/en/us/services.aspx

For some more details on the Fabric Controller I'd highly recommend Mark Russinovichs session about: http://channel9.msdn.com/Shows/Going+Deep/Mark-Russinovich-Windows-Azure-Cloud-Operating-Systems-and-Platform-as-a-Service
