As in my prior blog post about Azure’s lack of large disk support, this post follows the adventures of a friend of mine who was attempting to build an application stack atop Azure. Let’s call this friend Jim.

I naively responded, "I'm sure they'll work fine, you're not trying to do anything unusual." I warned him that his big challenge would be migrating the VMs from Azure back on-premise later because he'd have to convert the VMs to work inside VMware.
