• Segreated Event Layers – Mathias Verraes talks about internal events within a domain and using streams to consume them and expose different events.

• Patterns for Decoupling in Distributed Systems: Fat Event – Mathias Verraes goes into what state in an event could look like, the downsides and things to consider.

• Patterns for Decoupling in Distributed Systems: Passage of Time Event – An interesting event pattern to replace cron jobs and scheduled commands with event to indicate teh passage of time.

• Patterns for Decoupling in Distributed Systems: Summary Event – Rather than emitting a stream of events from a domain why not emit a single summary event at the end? Could you place your events with summary events?

• The different types of events in event-driven systems – Great read by Frank de Jonge as he goes into three types of events for our EDA applications, the domain event, trigger/signal event and RESTful or “Fat” event.

• Use a message envelope – Another great read by Frank de Jonge as he goes into message envelopes. Talks about what goes into an event, domain boundaries, decorators and much more.

• CQRS Documents by Greg Young – Very detailed document around CQRS and Greg goes into domain events, events as storage and much more

• Thin vs Fat Integration Events – Derek Comartin has some great content around event-driven architectures, in this blog post he walks though fat vs thin integration events with videos to support. Check out his YouTube channel too!

• The event notification pattern – Oskar uit de Bos gives us some great insight and thoughts into event notification pattern, recommended read!

• The Event-Carried State Transfer pattern – Another great read by Oskar uit de Bos, as he gives into the ECST pattern and highlights the good, bad and ugly.

• How Should My Event Be Designed? Some Thoughts on Event-Based Systems – Gökhan Gökalp gives us his thoughts on Event-Based systems and designs for our events.

• Event Collaboration And Event Sourcing – Lutz Hühnken looks at some event-driven architecture terminology that is often used very liberally, and provides a clear distinction.
