Each managed identity counts towards the object quota limit in an Azure AD tenant as described in Azure AD service limits and restrictions.
-
The rate at which managed identities can be created have the following limits:
- Per Azure AD Tenant per Azure region: 200 create operations per 20 seconds.
- Per Azure Subscription per Azure region : 40 create operations per 20 seconds.
-
When you create user-assigned managed identities, only alphanumeric characters (0-9, a-z, and A-Z) and the hyphen (-) are supported. For the assignment to a virtual machine or virtual machine scale set to work properly, the name is limited to 24 characters.
