This is typically referred to as the smart broker/ dumb consumers dynamic. With traditional message brokers, the event router is intelligent while the event consumers are more reactive than proactive. These traditional message brokers are persistent message frameworks that fuel the flow of events in an application's event-driven architecture. Some examples ofĬommon message queues include RabbitMQ and Redis. Transmit messages between event producers and event routers. ![]() This post was written alongside our other event-driven architecture articles, Introduction to Synchronous and Asynchronous Processing and Understanding Event-Driven Architecture and Serverless Opportunities Traditional Message Brokers are Persistent and Highly CentralizedĮarlier versions of event-driven architectures relied on message queues to We'll look at how these event routers work, their respective advantages and drawbacks before considering their better-fit use cases. That is why today we are going to review the differences between traditional message brokers like RabbitMQ and modern event streamers like Apache Kafka. Understanding their capabilities and limitations provides key insights that empower you to confidently decide which one to use and prepare you to navigate its shortcomings. ![]() Not all implementations of event routers are the same, nor do any of them offer an all-purpose solution, so deciding which one to use depends on your use case and project's needs. In an event-driven architecture, event routers are the components that connect event consumers to event producers.
