Set up VMware Identity Manager with the internal PostgreSQL database or an external Microsoft SQL database to store and organize server data. Both options can provide high availability.

An internal PostgreSQL database is embedded in the VMware Identity Manager appliance and is configured and ready to use by default. To achieve high availability with the internal PostgreSQL database, you must leverage vRealize Suite Lifecycle Manager. See the vRealize Suite Lifecycle Manager Installation, Upgrade, and Management guide.

To use an external database, your database administrator must prepare an empty external database and schema before connecting to the external database in the Setup wizard. Licensed users can use the Microsoft SQL database server to set up a high availability external database environment. See Create the VMware Identity Manager Service Database.
