4.4 Best Practices for Using S3 Standard Storage

1. Data Lifecycle Management: Implement lifecycle policies to automatically transition older data to more cost-effective storage classes like S3 Glacier for infrequent access.
2. Versioning and Backup: Enable versioning to protect against accidental deletions and overwrites. Regularly back up critical data.
3. Encryption and Security: Use S3’s encryption capabilities for data at rest and in transit. Implement IAM policies and bucket policies to control access.
4. Performance Optimization: Use transfer acceleration for faster uploads and downloads over long distances. Optimize performance for workloads with specific patterns, like using multipart uploads for large files.
5. Cost Management: Monitor and analyze your S3 usage with AWS Cost Explorer and S3 analytics. Optimize costs by reviewing and adjusting your usage patterns and storage types.
