The Microservices - Domain Event design pattern is used to achieve a reliable communication mechanism between microservices. This pattern ensures that different services can react to changes or events occurring in other services without needing to tightly couple their operations. By leveraging domain events, we can decouple services, ensuring scalability and maintainability.
Main Elements of the Pattern:
Domain Events: Represent significant state changes within a service that other services might be interested in.
Event Publisher: The component within a service that publishes the domain event to an event broker.
Event Broker: A middleware that handles the distribution of domain events to subscribing services.
Event Subscriber: The component within a service that subscribes to domain events and reacts accordingly.
Benefits:
Decoupling: Services do not need to directly communicate with each other, promoting loose coupling.
Scalability: Each service can be scaled independently.
Maintainability: Changes in one service do not directly affect other services, making the system easier to maintain.
