Have you used any queuing mechanisms such as SQS or SNS?
💡 Model Answer
Yes, I have used Amazon SQS and SNS in several projects. In one project, I used SQS to decouple microservices: a producer service pushed messages to an SQS queue, and a consumer service processed them asynchronously, ensuring reliability and scalability. I configured visibility timeouts and dead-letter queues to handle failures. For event-driven notifications, I used SNS to publish events to multiple subscribers, such as Lambda functions and email endpoints. I also integrated SNS with SQS to fan-out messages to multiple queues. These patterns helped improve system resilience, enable asynchronous processing, and reduce coupling between components.
