Broker Tour: AWS SQS (Managed Queues)

SQS Standard queues offer high throughput, at-least-once delivery, and best-effort ordering; duplicates possible. FIFO queues offer ordered, exactly-once processing via deduplication windows (no dup inserts within dedupe interval). All via HTTP APIs.

Use cases: decouple serverless functions, background jobs, simple retries with visibility timeouts.
