How can we improve Azure Virtual Machines?

Allow resize of attached VHD-disks

Right now you cannot resize your VHD-disks once attached to a VM directly from the portal. Edit should be possible to at least increase the size of VHD-disks on demand.

    As previously noted, Microsoft charges for the provisioned space of a managed disk. We cannot grossly oversize disks because of the cost. We need the ability to resize managed disks without deprovisioning the VM.

    This creates a problem when trying to retrieve a VHD back to on-prem - the fully-populated VHD size may exceed the disk space of the on-prem machine, even though the used data of the VHD is small.

    This is great if you are setting up a new server or have the ability to just rebuild a server(s) but what about exiting servers that need to be increased?

    So, say that my C: drive is already at 127GB, but I really need to increase it. What are my options?

    Does this work under Linux (Ubuntu, ext4 filesystem), i.e. can I safely allocate very large disk and assume that I will be billed for used space only?
