Description: An event broker is a component that facilitates communication between event producers and consumers. This design pattern is used to decouple the systems that generate events from those that process them, allowing for a more flexible and scalable architecture. Instead of producers sending events directly to consumers, events are sent to a broker that is responsible for distributing them to interested parties. This allows producers and consumers to evolve independently, as they do not need to be aware of each other’s existence. Event brokers often implement features such as event persistence, guaranteed delivery, and the ability to handle multiple types of events, making them an ideal solution for distributed systems and real-time applications. Additionally, this pattern is fundamental in event-driven architectures, where asynchronous communication and scalability are crucial. In summary, the event broker acts as an intermediary that optimizes interaction between different components of a system, improving software efficiency and maintainability.
