3.2. Summary

Modeling applications in Mule involves thinking about the different steps that need to be taken for the individual services Mule will host or interact with. Routers govern how the data will flow from one service to another, and transformers are needed to convert data from one format to another.

The Mule application can be built from such a model by using VM channels initially, to let you focus on the routing logic; you can replace these endpoints with the live transports when you are satisfied that the routing has been implemented properly.
