What message broker systems have you had experience integrating or interacting with?

In your practice, I have worked with several message broker systems:

• RabbitMQ: a popular broker supporting various protocols (AMQP, MQTT). Used for organizing task queues and message exchange between microservices.
• Apache Kafka: a high-throughput, resilient stream processing system. Used for logging and real-time event transmission.
• Redis Pub/Sub: a simple publish/subscribe mechanism, used for message exchange within a single application or small systems.

Each of these systems has its own features and is suitable for different scenarios — from simple queues to scalable event processing.
