Leverage managed identities in Unity Catalog

Unity Catalog provides unified governance for all data and AI assets in your Lakehouse.

Unity Catalog can be configured to use an Azure managed identity to access storage containers on behalf of Unity Catalog users. Managed identities provide an identity for applications to use when they connect to resources that support Microsoft Entra ID authentication.You can use managed identities in Unity Catalog to support two primary use cases:-

  • As an identity to connect to the metastore's storage accounts (where managed tables are stored).
  • As an identity to connect to other external storage accounts (either for file-based access or for external tables).

    • Configuring Unity Catalog with a managed identity has the following benefits over configuring Unity Catalog with a service principal:-

  • You can connect to an Azure Data Lake Storage Gen2 account that is protected by a storage firewall.
  • Managed identities do not require you to maintain credentials or rotate secrets.
