This post is a collection of content from David Boike from the Particular.net blog calling out some common problems and solutions for building message based distributed systems.

It goes a long way towards avoiding unwanted coupling between services. Slimming down your events Anybody can write code that will work for a few weeks or months, but what happens when that code is no longer your daily focus and the cobwebs of time ...

The integration makes systemd aware when the application has started/is stopping, and configures logs to be sent in a way that journald (the logging system of systemd) understands log priorities.
