One of these connections is shared for all workspaces in the region.ĭatabricks strongly recommends creating a workspace called a private web auth workspace for each region to host the web auth private network settings. A special type of private connection with sub-resource type browser_authentication hosts a private connection from the transit VNet that allows Azure Active Directory to redirect users after login to the correct control plane instance. Web auth private connections: To support private front-end connections, special configuration is required to support the single sign-on (SSO) login callbacks to the Azure Databricks web application.

This enables private connectivity from the clusters to the secure cluster connectivity relay endpoint and REST API endpoint. The network traffic for a front-end Private Link connection between a transit VNet and the workspace control plane traverses over the Microsoft backbone network.īack-end Private Link, also known as data plane to control plane: Databricks Runtime clusters in a customer-managed VNet (the data plane) connect to an Azure Databricks workspace’s core services (the control plane) in the Azure Databricks cloud account. The front-end connection is also used by JDBC/ODBC and PowerBI integrations. Azure Databricks supports the following Private Link connection types:įront-end Private Link, also known as user to workspace: A front-end Private Link connection allows users to connect to the Azure Databricks web application, REST API, and Databricks Connect API over a VNet interface endpoint. Private Link provides private connectivity from Azure VNets and on-premises networks to Azure services without exposing the traffic to the public network. By contrast, the serverless data plane that supports serverless SQL warehouses runs in the Azure subscription of Azure Databricks. In the context of this article, data plane refers to the Classic data plane in your Azure subscription. This article mentions the term data plane, which is the compute layer of the Azure Databricks platform.
