When should you use RabbitMQ as a messaging system between microservices?

RabbitMQ should be used in the following cases:

• When reliable asynchronous communication between microservices is required.
• If message delivery guarantees are important (e.g., receipt confirmation).
• When message routing across different queues and exchanges is needed.
• When load balancing and scalability of consumers are necessary.
• If implementing pub/sub patterns, task queues, or delayed processing.

Example: a microservice receives requests from users and places tasks in the RabbitMQ queue, while another microservice processes them asynchronously, without blocking the main thread.
