With DDOS 7.7 (and later), a DDVE deployed on Azure supports two methods of authentication to the storage account.
Using OAuth 2.0 (recommended)
Open Authorization (OAuth) 2.0 is an industry standard for authentication between clients and servers.
OAuth 2.0 uses an authorization framework in which a client (for example, a compute VM instance) requests an authorization grant from the resource owner (for example, Azure) to access a protected resource (for example, Azure cloud storage). The client then uses the authorization grant to request an OAuth 2.0 token from an authorization server (for example, the Azure metadata server).
The resource owner delegates the authorization server to issue an OAuth 2.0 token that is based on the permissions of the authorization grant. The OAuth 2.0 token has a limited lifetime and specific permissions that are based on the authorization grant.
You can assign only one type of managed identity. If you configure a system-assigned managed identity, you cannot configure a user-assigned managed identity for the same DDVE.
