The NMR mediates communication so that the location of each service
doesn't matter. Use of the NMR is done via a flow and the three main
flows provided by ServiceMix (i.e., SEDA, JMS and JCA) each provide a
certain level of threading and buffering for messages via
java.util.concurrent queues.
Consider a situation where you have multiple instances of ServiceMix
running. When networking the containers together, the NMR allows
services running in one container to communicate with services running
in another container very easily. If you make those two services talk
directly to one another without using the NMR, then you are completely
circumventing the inherent benefits provided by the NMR. In a way,
this would be no better than running web services in stand alone web
containers and making them talk directly to one another.
