Command Bus and Action-Domain-Responder

In his recent blog post, Paul M Jones is describing about Command Bus pattern and Action-Domain-Responder pattern. In this post, he is describing how they fit with each other and suggesting Command bus should be part of domain.

Over the past few weeks, different people have asked me where a Command Bus goes in an Action-Domain-Responder system. While I’m not a DDD expert, after brushing up on the subject a little, my answer is: “In the Domain.”
