3 Azure databricks instances in 3 tenants - 1 VNET Data Gateway to connect from Power BI service

[EduardD]

Hi there, we have 3 Databricks environemnts one per individual Azure Tenant (Dev, Test, Prod). We want to use Power BI service only in Prod tenant to visualize data from all 3 Databricks, to connect we plan to use 1 VNET Data Gateway that should reach all 3 databricks instances.
My understanding that we need to create one VNET that contains all 3 Databricks private endpoints and inject VNET Data gateway into that.  Is it right? Is it something that can be done?  If not, are there any other options?

Hi @EduardD,

Hope you are doing well!

Try this approach step by step:

- Create a "hub" VNet in your Prod tenant (where Power BI Service lives)

- Inject the VNET Data Gateway into this hub VNet

- In each tenant (Dev, Test), create a private endpoint for Databricks in a VNet local to that tenant

- Peer the Dev and Test VNets to the Prod hub VNet using cross-tenant VNet peering

Remember that :

Cross-tenant VNet peering is supported in Azure, but requires an administrator from each tenant to approve the peering connection. Traffic flows privately end-to-end.

Result: One gateway, three Databricks reachable over private network.

Hope this helps! Feel free to ask more questions if needed. Don't forget to mark as solution in order to motivate me to keep helping 🙂
