designed for noncritical, reproducible data stored at lower levels of redundancy than the STANDARD storage class.S3 Reduced Redundancy Storage (Not Recommended).stores data in a single AZ, data stored in this storage class will be lost in the event of AZ destruction.ideal for secondary backups and reproducible data.optimized for rapid access, less frequently access data.S3 One Zone-Infrequent Access (S3 One Zone-IA).suitable for objects greater than 128 KB kept for at least 30 days.optimized for long-lived and less frequently accessed data.S3 Standard-Infrequent Access (S3 Standard-IA).designed to sustain the loss of data in a two facilities.Low latency and high throughput performance.default storage class, ideal for frequently accessed data.Integrates with CloudTrail, CloudWatch, and SNS for event notifications.
MFA (Multi-Factor Authentication) can be enabled for additional security for the deletion of objects.protects individual files but does NOT protect from Bucket deletion.protect from unintended overwrites and accidental deletions.helps preserve, retrieve, and restore every version of every object.begin an upload before the final object size is known.fault tolerance and quick recovery from network issues.
parallel uploads with improved throughput and bandwidth utilization.Pre-Signed URLs can be used shared for uploading/downloading objects for a limited time without requiring AWS security credentials.S3 Batch Operations help perform large-scale batch operations on S3 objects and can perform a single operation on lists of specified S3 objects.
