Which message broker did you use?

In my practice, I have used several message brokers depending on the project requirements:

• RabbitMQ — for projects where reliable message delivery is important, supporting various exchange models (queues, topics), and scalability.
• Apache Kafka — for systems with high loads and the need to process large streams of data in real-time.
• Redis Pub/Sub — for simple cases where quick message transfer is needed without delivery guarantees.

The choice of broker depends on the requirements for reliability, performance, architecture complexity, and the project's ecosystem.
