I reckon your message broker might be a bad idea.

Message brokers can be a bad idea if treated like "infallible gods", because they aren't. Think about three good design principles for realiable systems:

• Fail fast
• Process supervision
• End-to-End principle

In the end, it isn’t so much about message brokers, but treating them as infallible gods. By using acknowledgements, back-pressure and other techniques you can move responsibility out of the brokers and into the edges. What was once a central point of failure becomes an effectively stateless server, no-longer hiding failures from your components. Your system works because it knows that it can fail.
