Event-based Architecture and Implementations with Kafka and Atom

This presentation examines the design choices behind event-based architecture and whether events deliver strong decoupling. It considers communication between bounded contexts, data consistency, and implementations with Kafka and Atom.

Syllabus

Intro
Independent Systems Architecture
Events - Communication between Bounded Contexts
Event: Decoupling
Events: Conclusion
THE END IS NEAR
Inconsistencies Either delivery without invoice
Persistence • Responsibility of the microservices
Kafka Topics Topics have a name
Kafka Replication ·N Replicas (configurable)
Data Data is copied into Invoice / delivery database
Kafka Conclusion - Provides access to old events
Alternative Roll your own format
Atom Conclusion Con provides access to old events if they are stored anyway.
