What role did RabbitMQ play in your previous project and what tasks was this tool used for?

In my previous project, RabbitMQ was used as a message broker to organize asynchronous interaction between microservices. The main tasks for which RabbitMQ was applied:

• Task queue for processing to unload main services and ensure resilience to peak loads.
• Transmission of events between system components, for example, notifications about data changes.
• Implementation of the Publish/Subscribe pattern for distributing messages to multiple subscribers.

Example: the order reception service sent a message to the queue, and the order processing service processed them asynchronously, which increased the scalability and fault tolerance of the system.
