What is the role of the "Service Broker" in SOA Model Architectur开发者_如何学运维e?

The service broker is meant to be a registry of services, and stores information about what services are available and who may use them. For example, UDDI which was originally conceived as a web service registry is now considered a SOA Service Broker.

SOA registry is responsible for registering business services, while SOA broker is responsible for orchestrating the connections between these components.. The service broker reads the interface information from the registry and then makes the right connection to other interfaces.
