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 setups, turn on versioning, set lifecycle rules, and plan cross-region replication for durability, cost, and rules.

Stream logs with Fluentd, Fluent Bit, or CloudWatch Logs, and send large files to S3 using presigned URLs from apps.

Use S3 Transfer Acceleration, CloudFront caching, local caches, and S3 Select to speed up partial reads and cut transfer costs.

See gp3 vs gp2, io2 or io2 Block Express for high IOPS, and st1 or sc1 for big throughput sequential work.

Check burst, queue depth, and costs to hit performance without extra spend.

Compare SSE-KMS and SSE-S3, manage keys, and limit network paths.

Learn best volume types, mount plans, and how separation boosts speed, durability, and flexibility.

Learn snapshot habits, backup automation, and how root design affects recovery.

Learn patterns for caching, scratch space, temp queues, and ways to copy or save data to lasting storage.

Estimate start size, watch usage, set lifecycle rules, and resize live with Elastic Volumes.

Compare ext4 and XFS, pick mount options for speed and safety, and set journaling, TRIM, alignment for recovery.
