??? Content Enricher. This intermediary offers augmentation of data capabilities. It typically
pulls in information from various repositories to enrich an original message that has been
sent from a consumer or a service.
??? Gateway Enabler. A gateway is a bridging entity, an interceptor that enables communications
between two or more heterogeneous computing environments. Although it
is akin to the message transformer intermediary, its role is related more to bridging
communications between operating systems, applications, and platforms.
??? Transaction Monitor. This broker intercepts messages to provide tracking mechanisms
for production environments. It characteristically facilitates three major activities: audit
trail, history reporting, and security monitoring.
??? Service Locator. The locator is responsible for searching consumers??™ corresponding services
and service offerings. It is often called business locator. Traditionally, the well
known service fac??ade acts as a service locator to identify the requested business logic.
??? Message Router. The routing role is consumed with dispatching messages to their
end-point services. Intermediaries that provide message distributing capabilities also offer
load balancing and workload management features.
??? Message Filter. This message broker enables the censorship of transported information
based on business rules. This filtering activity is obviously performed before a message
arrives to its destination.
