1Default limits vary by offer Category Type, such as Free Trial, Pay-As-You-Go, and series, such as Dv2, F, G, etc.
2This includes both Standard and Premium storage accounts. If you require more than 200 storage accounts, make a request through Azure Support. The Azure Storage team will review your business case and may approve up to 250 storage accounts.
3You can apply an unlimited number of tags per subscription. The number of tags per resource or resource group is limited to 15. Resource Manager only returns a list of unique tag name and values in the subscription when the number of tags is 10,000 or less. However, you can still find a resource by tag when the number exceeds 10,000.
4These features are no longer required with Azure Resource Groups and the Azure Resource Manager.
Note
It is important to emphasize that virtual machine cores have a regional total limit as well as a regional per size series (Dv2, F, etc.) limit that are separately enforced. For example, consider a subscription with a US East total VM core limit of 30, an A series core limit of 30, and a D series core limit of 30. This subscription would be allowed to deploy 30 A1 VMs, or 30 D1 VMs, or a combination of the two not to exceed a total of 30 cores (for example, 10 A1 VMs and 20 D1 VMs).
