Describe your experience with using queues in projects and their role in application architecture.

Queues are often used in projects to organize asynchronous task processing and to offload main services. They allow:

• Separating task generation from their execution.
• Ensuring reliability and retry mechanisms.
• Scaling the system by adding more handlers.

For example, in a web application, emails can be sent through a queue to avoid delaying the response to the user. In queue architecture, they act as intermediaries between components, providing reliable and ordered message transfer.

Popular tools include: RabbitMQ, Kafka, Redis Streams. In DevOps, queues help manage load and increase system fault tolerance.
