Set the Azure Relay for on-premises data gateway

  • Article

During installation of the on-premises data gateway, the Azure Relays are automatically provisioned. However, you can also provide your own relay details. These details help you associate the relay with your Azure subscription and also manage the sender and listener keys for this relay.

Note

Only WCF relays with NetTcp type are supported for this feature.

Steps to provide your own relay details

  1. Select Provide Relay details.

    Select Provide Relay details.

  2. You can now provide more details about your relay.

    Provide additional relay details.

    1. WCF Relay endpoint URI—Provide the URI (highlighted below) for your WCF relay from the Azure portal.

      Provide the WCF relay URI.

      Note

      The WCF Relay endpoint URI must be unique for every gateway and can't be re-used for other gateways.

    2. Send key value and the Listen Key Value—Create two shared access policies, one called SendAccessKey and the other ListenAccessKey. Provide either the primary or the secondary keys in the on-premises data gateway app. To learn more, go to Azure Relay authentication and authorization.

      Send and listen access keys.

Note

If you recover an existing gateway with customized relay details to a new machine, you'll have to explicitly uninstall the gateway from the old machine or rotate the sender and listener keys. If this operation isn't done, then queries through this gateway may fail.

Keep data in the region where it's stored

If you want to keep your data within the region where it’s stored, all you need to do is:

  • Bring your own relay that lives in the same region as the data.
  • Make sure your capacity is in the same region.

When you install an on-premises data gateway, you must select the region of the home tenant to work with Power BI. Data from your gateway must travel to the relay, then to the location of your Power BI capacity. An Azure Relay automatically gets installed in the same region selected for the on-premises data gateway during its configuration.

However, you have the option to choose your own relay in a different location. Then, the data will transfer through the location of your assigned relay instead. Only metadata will go to the gateway application in the home region and this condition can't be changed. This means you can keep your data within the region it's stored in if your relay, the capacity, and the data are all in the same region.
