Main message brokers:
-
RabbitMQ — a classic broker based on AMQP. Supports reliable delivery, queues, routing, message acknowledgments. Good for complex scenarios with delivery guarantees.
-
Apache Kafka — a distributed broker with high throughput and resilience. Used for stream processing, stores message logs, supports scaling and replication.
-
ActiveMQ — an Apache broker supporting multiple protocols (AMQP, MQTT, STOMP). Good for integrating different systems.
-
Redis Pub/Sub — a simple broker based on Redis, operates on a publish-subscribe principle, but does not guarantee message delivery.
-
Amazon SQS — a cloud queue service from AWS, fully managed, scalable, with delivery guarantees.
Differences mainly relate to architecture, delivery guarantees, scalability, supported protocols, and use cases. For example, Kafka is better suited for processing large data streams, RabbitMQ for complex routing and guaranteed delivery.
