Event-Driven Architecture & Message Queues: Kafka, RabbitMQ Explained

Image
  In today's fast-paced, data-rich applications, Event-Driven Architecture (EDA) offers a scalable and decoupled way to handle events as they occur across distributed systems. What is Event-Driven Architecture (EDA)? EDA revolves around the production, detection, and reaction to events . Instead of request/response cycles, systems emit events and others subscribe or react to them asynchronously. Core Components Producer: Sends or emits events. Event Broker (Queue): Middleware that routes and stores events. Consumer: Listens and reacts to the events. Why EDA? Loose coupling Improved scalability Real-time processing Better fault tolerance Popular Message Queues 1. Apache Kafka High throughput Distributed, partitioned, replicated commit log Ideal for event streaming and analytics 2. RabbitMQ Easy to use Strong support for routing via exchange types Ideal for transactional workflows and lightweight messaging Kafka vs. RabbitMQ: Quick Comparison Minimize image Edit image Delete ima...
