This covers AWS SNS for pub/sub messaging, which you'll reach for when one event needs to trigger multiple actions. The skill walks through creating standard and FIFO topics, setting up subscriptions across Lambda, SQS, HTTP endpoints, and email, plus message filtering with attribute-based routing. The fan-out pattern is well explained with a concrete example of broadcasting order events to analytics, fulfillment, and notification queues simultaneously. Filter policies get good coverage with numeric comparisons, prefix matching, and exists checks. What's helpful is the emphasis on pairing SNS with SQS for durability, since SNS itself is push-only and won't hold messages if a subscriber is down. The examples are boto3 heavy with some CLI snippets.
