Peer virtual networks

  • Article

This article shows you how to peer an Azure Databricks virtual network (VNet) with an Azure VNet.

Overview of virtual network (VNet) peering

The default deployment of Azure Databricks is a fully managed service on Azure. Classic compute plane resources are deployed in a managed Azure Databricks virtual network (VNet). You can also choose to deploy Azure Databricks in your Azure virtual network (also known as VNet injection), see Deploy Azure Databricks in your Azure virtual network (VNet injection).

VNet peering allows the virtual network that your Azure Databricks workspace is running to peer with another Azure virtual network. For an overview of Azure VNet peering, see Azure Virtual network peering.

You can peer a managed Azure Databricks VNet to another to an Azure VNet or you can peer your own Azure VNet (in a VNet-injected workspace) to another to an Azure VNet.

Traffic between virtual machines in the peered virtual networks is always over the Azure network backbone and not the public internet.

Peer an Azure Databricks virtual network to another Azure virtual network

  1. In the Azure portal, find the Azure Databricks workspace service.
  2. In the Settings section of the sidebar, click Virtual Network Peering.
  3. Click + Add peering.
  4. Enter a name.
  5. Depending on the information you have about the remote virtual network, do one of the following:
    • If you know the resource ID of the remote virtual network:
      1. Select the I know my Resource ID checkbox.
      2. In the Resource ID text box, paste in the remote virtual network resource ID.
    • If you know the name of the remote virtual network:
      1. In the Subscription drop-down, select a subscription.
      2. In the Virtual network drop-down, select the remote virtual network.
  6. Specify the configuration of the remote virtual network. See Create a peering for information about the configuration fields.
  7. Click Add.

To confirm that the peering is deployed and connected, go to the Azure Databricks workspace resource in the Azure portal, select Virtual Network Peerings, and verify that the peering's status is Connected.

Peer your own virtual network to another Azure virtual network

You can deploy Azure Databricks in your Azure virtual network (also known as VNet injection). To set up VNet peering in a VNet-injected workspace, configure the peering in the virtual network you deployed Azure Databricks in. See Create, change, or delete a virtual network peering.

Connect an on-premises virtual network to an Azure virtual network

To connect an on-premises network to an Azure VNet, follow the steps in Connect an on-premises network to Azure using ExpressRoute.

To create a site-to-site VPN gateway connection from your on-premises network to an Azure VNet, follow the steps in Create a Site-to-Site connection in the Azure portal.
