Microsoft's Windows Azure team has introduced VM Role and elevated privilege to make the process of migrating existing Windows Server applications to Windows Azure easier and faster.
The pricing model for the Azure VM role is the same as the existing pricing model for Web and Worker roles. Customers will be charged at an hourly rate depending on the compute instance size. The license for the Windows Server 2008 R2 that you us to create the VM is covered through the Azure VM Role licensing."
Elevated Privileges let you configure IIS or install your apps using an MSI and will be available soon.
About VM Role on Windows Azure:
A Virtual Machine (VM) role runs an image--a virtual hard disk (VHD)--of a Server 2008 R2 vm. This VHD is created using an on-premises Windows Server machine, that you upload to Azure. You've full control of the operating system image. Admins can remote into the vm of all roles to perform maintenance and troubleshooting tasks.
Once it's stored in the cloud, the VHD can be loaded on demand into a VM role and executed. You can configure and maintain the OS and use Windows Services, scheduled tasks etc. in the VM role.
Running a VM role isn't supported in the compute emulator.
About Elevated Privileges:
New Elevated Privileges will be available soon for the Web and Worker role for you to develop, deploy, and run you cloud apps. For small changes like configuring IIS or installing an MSI we recommend using the elevated privilege admin access feature.
The Web role will also include Full IIS functionality, which enables multiple IIS sites per Web role and the ability to install IIS modules.
