Message Broker

A message broker is an intermediary software component that facilitates communication between distributed applications by receiving, routing, and delivering messages. It decouples message producers from consumers, enabling asynchronous communication and improving system scalability and reliability. Common implementations include RabbitMQ, Apache Kafka, and ActiveMQ.

Also known as: Message Queue, MQ, Event Broker, Message-Oriented Middleware, MOM

Why learn Message Broker?

Developers should use message brokers when building distributed systems, microservices architectures, or event-driven applications that require reliable, scalable, and asynchronous communication. They are essential for handling high-throughput data streams, implementing publish-subscribe patterns, and ensuring fault tolerance in cloud-native environments.
