BizTalk architecture

We'll now examine the BizTalk architecture and look at how all the components relate to each other.

BizTalk message flow

The next diagram illustrates a standard message flow through the main components of BizTalk. The BizTalk messaging system has three distinct parts: receive port, MessageBox, and send port.

Messages are received via a receive port. A receive port can contain one or more receive locations, which provide the ability to have multiple transport entry points into the application. For example, some customers choose to have a WCF-Custom receive location but they also have a file receive location for manual re-submission of messages. A receive location is a combination of an adapter and specific pipeline configuration. Certain artifacts can be configured at the receive location level, for example the pipeline used and the adapter configuration. Others, such as the map used and enabling failed message routing need to be configured at the port level.
