Multitenant private endpoint

Question

I have a subscription in Tenant A that needs to access a SQL database in Tenant B's subscription. To achieve this, I am creating a private endpoint in Tenant B's subscription. What should the architecture look like? And do the VNets in Tenant A and Tenant B need to be peered for Tenant A to access the SQL database in Tenant B?

Hi @ Merin Mary

Thanks for the Question and using Microsoft Q&A platform

As per my understanding, you need to access SQL database in Tenant B's subscription from the subscription in Tenant A.

To access SQL database in Tenant B subscription, you need to create a Private Endpoint for the SQL database in Tenant B's subscription. This endpoint will give the database a private IP address within Tenant B's Virtual Network (VNet).

The VNets in Tenant A and Tenant B must be peered. This is necessary for secure communication between both VNets. You will need to establish VNet peering to allow Tenant A to access the database through the private endpoint.
