Synchronization keeps data consistent across disparate resources. Within Identity Cloud, we refer to two resource types—managed resources (stored in the Identity Cloud repository) and external resources. An external resource can be any system that holds identity data, such as ForgeRock Directory Services (DS), Active Directory, a CSV file, a JDBC database, and so on.
Identity Cloud connects to external resources through connectors. For information about these connectors, see the Connectors Guide. Synchronization across resources happens when managed resources change, or when Identity Cloud discovers a change on a system resource. There are various synchronization mechanisms that ensure data consistency.
