Exploring event-driven architecture patterns
Event-driven architecture leverages various design patterns to effectively handle events and ensure robust, scalable, and maintainable systems. These patterns help manage event generation, transmission, processing, and storage complexities. We will present some commonly used patterns in event-driven architecture.
Publish-subscribe
The publish-subscribe pattern in event-driven architecture involves producers sending events to a broker, which distributes the events to multiple consumers. Messages are pushed to consumers, and consumers can be added or removed without affecting the producer. A durable subscription allows inactive consumers to receive missed events upon reconnection.
An example is a social media platform where users subscribe to updates from other users. When a user posts a new update, it is published to all subscribers.
Event notification
