The following figure illustrates OpenSSO Enterprise deployed with the embedded configuration data store in single-server mode.

Figure 15–1 Single-Server Mode

Under multiple-servers mode, every OpenSSO Enterprise instance works with its own embedded configuration data store instance under the same memory space in the web container. The embedded configuration data store replication mechanism uses the custom replication protocol to maintain the data consistency between directory service instances.

The following figure illustrates OpenSSO Enterprise deployed with the embedded configuration data store in multiple-servers mode.
