First of all, I’m a BizTalk developer so I will review Azure Service Bus EAI & EDI Mapper from a BizTalk developer’s perspective. As a start it is important to mention that Azure Service Bus EAI & EDI came out in December 2011 for the first time. It is still in its early phase and it offers some EAI-possibilities by offering an orchestration-like designer and endpoint integration through WCF LOB Adapters. For those who have never heard of WCF LOB adapters, it is an adapter pack that ships with BizTalk Server 2010 installation media offering adapters for SAP, Siebel, etc. Now let’s go back to the new Mapper and take a peak on what it looks like.
