Figure 5-4 shows a product mapping for this Runtime pattern using Web
Services Gateway.

Note that WebSphere Business Integration Message Broker can also provide
Router functionality.

5.3.1 Runtime patterns and product mapping for Exposed Broker
The Exposed Broker application pattern can be thought of as an extension to the
Broker application pattern. It extends the solution to include external partners by
exposing their processes to the broker.
Figure 5-5 shows the basic Runtime pattern for the Exposed Broker application
pattern.

The Exposed Broker node encompasses the functionality of a Broker node, and
in addition, includes the means to expose partner processes to internal
processes.

Figure 5-6 shows a product mapping for this Runtime pattern using the
WebSphere Business Integration Message Broker and the Web Services
Gateway products.
Figure 5-6 Extended Enterprise::Exposed Broker product mapping
WebSphere Business Integration Message Broker provides the same
functionality outlined in 5.2.1, “Runtime pattern and product mapping for the
Broker” on page 95. The Web Services Gateway is used to provide a standard,
consistent interface for the internal processes to access external processes. The
use of a gateway minimizes the disruption caused by changes in the external
partner infrastructure.
5.3.2 Runtime pattern and product mappings for the Router variation
The Router variation of the Exposed Broker application pattern can be thought of
as an extension to the Router variation of the Broker application pattern. It
extends the solution to include external partners by exposing their processes to
the router.
