Configure and Manage Message Queues with Amazon Simple Queue Service (SQS)

Why it matters

Message queues are part of the long-running inference-worker pattern in 2.4.2. This exercise provides general messaging practice relevant to connecting queued work to its processor.

What to practise

In an e-commerce scenario, configure SQS queues as Lambda event sources. Build SNS fan-out with multiple SQS subscribers, filter messages for targeted queue delivery, and implement automated processing of failed messages through dead-letter queues. Watch which queue each filtered message reaches and which messages end up in a dead-letter queue.

How it fits

For a GenAI workload, focus on the queue-to-Lambda connection and the dead-letter handling of failed messages behind 2.4.2. The exercise provides that infrastructure background; durable inference completion records and correlation IDs remain application design work.
