Previously, objects had to remain in S3 Standard for at least 30 days before transitioning to infrequent access tiers. The removal of this minimum enables immediate cost savings for data that becomes cold quickly, such as backups and logs.
These storage classes maintain millisecond access speeds but at up to 40% lower costs than S3 Standard. Users can configure lifecycle rules to move objects to IA tiers as soon as creation, optimizing storage economics without sacrificing data availability. The update applies across all regions supporting these classes.
