Episode 42: Interview Gregor Hohpe

In this episode, Gregor Hohpe gives us a great introduction to
enterprise messaging based on his EAI Patterns book. Before we
started discusssing the patterns in his book, we characterized
messaging and talked about the various interaction styles. We also
contrasted the messaging architectural style with an RPC based
approach. We then took a look at the relationship to SOA, the role
of contracts and the orchestration-vs-choreography discussion. We
briefly discussed the nature of pattern languages before we then
went through the different section in the book. There are six main
sections: channel, message, routing, transfomation, endpoint as
well as management and monitoring. We discussed the core patterns
for each of these sections. This should give listeners a good
high-level view of message-based systems. We concluded the
discussion by looking at the critical importance of systems
management and monitoring.
