Summary

In this chapter, we walked through how to implement a supply chain scenario using either an inflexible monolithic approach or a Message Bus-based approach by leveraging the ESB Toolkit 2.1 for BizTalk Server 2010. In particular, we demonstrated the Itinerary Broker Service functionality, which enables routing and can remove the need for Orchestration in some simplistic scenarios. We demonstrated the re-use of previously generated artifacts within different ESB itineraries. We deployed the itineraries easily without recompilation or redeployment of solution code.

We have scratched the surface here on the ESB toolkit functionality. It provides many additional capabilities including the abilities to use Orchestrations within itineraries, resolve itinerary based on Business Rules Engine (BRE) Policies, and a complex exception handling framework and management portal.
