Change all templates to use Azure Managed Disks, this will simplify things since there is no need to manage storage accounts anymore.

Recently, Azure Managed Disks were announced. I’ve been testing this in my own lab and I have transitioned my own ARM Template to use Managed Disks. This significantly improves reliability and reduces complexity because you no longer have to create and maintain Storage Accounts! This also makes the step towards a separate Resource Group for RDSH Servers (that we discussed before) much easier because these is no dependency of a storage account. And it also comes in handy for the template that updates the RDSH with a custom template image. That is now simply a resource of type Image in Azure, without a storage account. I think we can really benefit from adding Managed Disks to our templates.

I just published an article on how I transitioned my RDS Template to using Managed Disks: http://microsoftplatform.blogspot.nl/2017/03/azure-resource-manager-and-json_15.html

rds-deployment has been converted to use MD.

We decided to hold off on this change until the v2 RDS templates.
