Global and Brokered ESBs | BEA

• Global ESB: All services share one namespace, and each service provider is visible to every service requester across a heterogeneous, centrally administered, geographically distributed environment. Used by departments or small enterprises where all the services are likely to be applicable throughout the organization.

• Brokered ESB: Bridge services that selectively expose requesters or providers to partners in other domains regulate sharing among multiple ESB installations that each manages its own namespace. Service interactions between ESBs are facilitated through a common broker that implements the bridge services. Used by departments that develop and manage their own services, but share a few of them, or selectively access services provided across the enterprise.
