Lesson 1S3 usage patterns: storing uploads, logs, and static assets; lifecycle policies, versioning, and cross-region replication (CRR) considerationsMaster usual S3 patterns for uploads, logs, and static assets. Design bucket layouts, turn on versioning, set lifecycle policies, and plan cross-region replication to match durability, cost, and compliance needs.

Stream logs via Fluentd, Fluent Bit, or CloudWatch Logs, and shift large binaries to S3 using presigned URLs from apps.
