Over the last few weeks I've been going over a few different ways to solve inter service communication. So which one is best then?
In order to distinguish pub/sub from message bus communication I will assume the pub/sub does not use another component to distribute the data as that would be a message bus pattern. I will assume that the publisher knows about all subscribers either statically or dynamically.
So time to look back again and update some old opinions from June 2008. And while there are some other useful stuff in there I'll focus on code coverage and testing simple things. Because I feel the urge to explain myself...
