Lesson 1S3 usage patterns: storing uploads, logs, and static assets; lifecycle policies, versioning, and cross-region replication (CRR) considerationsMaster common S3 usage patterns for uploads, logs, and static assets. Learn to design bucket layouts, enable versioning, configure lifecycle policies, and plan cross-region replication to balance durability, cost, and compliance.

Understand gp3 versus gp2, when to use io2 or io2 Block Express for high IOPS, and how st1 or sc1 fit throughput-heavy, sequential workloads.
