The Service Consumer and Service Provider leverage the data tier constructs of the Staging Area and the Intermediate Area to exchange the bulk of the data needed to fulfill the business call interaction. In addition, they use the Integration Layer components such as the ESB to help mediate, monitor, and manage the call notifications and the call prioritizations.

Conclusion

In conclusion, this pattern when applied to certain use cases allows the enterprise to embark on SOA style implementations where by interactions with specialized Service Providers require trading all of the relevant business or application data during the execution of the call due to the limitations of the hosting platform of the Service Provider. In these circumstances, the use of the Staging Area and Intermediate Area constructs enable using more optimized interactions with "niche" service providers that offer computation-oriented functionality (process bound) or federated information gathering type functionality. Thus, application of this architecture model allows interactions with these type of "utility" service providers to still utilize SOA principles of loose coupling without sacrificing the core strengths of these specialized Service Providers.
