An S3 bucket contains objects that are frequently accessed for the first 30 days and rarely accessed afterward. Which lifecycle policy minimizes storage cost?
Answer: Transition objects to S3 Glacier Instant Retrieval after 30 days

An application needs to perform complex fan-out notifications: when an order is placed, it must notify inventory, billing, and shipping services simultaneously. Which pattern is most appropriate?
