In the event that distributed, redundant or scalable data centers are necessary, several OSGD servers will be connected together to an OSGD array. If this is not possible due to technical or organizational reasons, this leads to the creation of OSGD Islands. Their host and application definitions are then no longer centrally managed.

If the Visulox OSGD datastore replicator is used, a unified updating of the systems can be achieved.

All applications and hosts are defined in the OSGD system. The application mapping is accomplished via Directory Service Integration (DSI). This configuration is stored in the OSGD datastore, retrieved again over the OSGD Web service and sent to the OSGD systems in operation. The datastore is thus replicated. Through appropriate naming and a modification in the Webtop of the OSGD system, only the applications that are valid for this OSGD system will be displayed to the users.
 Requirement for a sensibly distributed OSGD infrastructure, with independent OSGD arrays, is a common User repository to which all OSGD arrays are connected to.

The sketch shows a solution with the LDAP master-master replication and the Visulox OSGD datastore replication. The configuration is then only performed over the OSGD System Admin console of the master.
