Lesson 1S3 usage patterns: storing uploads, logs, and static assets; lifecycle policies, versioning, and cross-region replication (CRR) considerationsMaster S3 patterns for uploads, logs, and static files. Design bucket structures, enable versioning, set lifecycle policies, and plan cross-region replication for durability, cost, and compliance in Eritrean apps.
