We are enrolled into the Microsoft Bizspark startup program which grants Azure credits to up to 7 members. We want to maximize those benefits by using different subscriptions / accounts for different purposes. For instance, one subscription for Azure Websites, and another subscription for a VM containing the MySQL database for those websites.
Question: is there any way to share an affinity group among multiple subscriptions/accounts in order to insure that the websites and database VMs in the example above will be placed near each other in the same datacenter?
