Design Microservices Architecture with Patterns and Principles - RabbitMQ Exchange Types - Direct, Fanout, Topic, and He

The video tutorial explains the four types of exchanges in RabbitMQ: direct, topic, fan out, and header exchanges. Each exchange type has a specific routing algorithm that determines how messages are routed to queues. Direct exchange routes messages to a single queue using a routing key. Topic exchange routes messages based on their subject, suitable for publish-subscribe patterns. Fan out exchange broadcasts messages to multiple queues, ideal for global announcements. Header exchange uses message headers for routing, matching attributes between headers and queues.
