Candidate architectures

We have two viable choices when looking to implement a Scatter-Gather pattern using an aggregator. One of them is the new Windows Server AppFabric release and the other is the BizTalk orchestration engine.

Candidate architecture #1 BizTalk Server

BizTalk is Microsoft's Enterprise Integration tool and has a robust messaging and workflow (orchestration) engine. Maccoll Bank is already, largely a Microsoft-based technology firm. BizTalk provides full and complete integration with Microsoft and other heterogeneous technology through its adapter framework. For the purpose of this analysis, the assumption will be that BizTalk is not already in use within the organization.
