S3

This covers the essentials of S3 operations: bucket creation with proper security defaults, object uploads and downloads, presigned URLs for temporary access, and lifecycle policies for cost management. The doc walks through both high-level CLI commands and low-level s3api calls, plus boto3 examples for Python automation. What stands out is the security-first approach, showing how to block public access, enable versioning, and configure encryption right from the start. The lifecycle policy examples are especially practical, covering transitions to Glacier and cleaning up old versions. If you're setting up S3 infrastructure or automating file operations, the presigned URL and event notification patterns will save you time.
