Grouping of cloud services within a single subscription
Example: You are a company with a BizSpark Azure subscription that offers discounted pricing. You also deal with multiple clients and host cloud services on their behalf under the BizSpark Azure subscription.
Task: You need to know how much each client has to pay for hosting their cloud services.
Problem: There is no way to know how much money was used on a set (or group) of cloud services/offerings under a single subscription. The subscription billing Excel export combines all cloud services in a very complicated view.
Thanks for the feedback. Tags & resource groups now flow through to the detailed usage for services such as V2 IaaS VMs. More services are coming online over the next few months.
