Intelligent Tiering Configuration - Table of Contents Intelligent Tiering Overview The S3 Intelligent-Tiering storage class designed to optimize storage costs by automatically moving data to the most cost-effective access tier. It monitors usage patterns of the objects and automatically moves object to the most cost-effective access tier. By default the Intelligent-Tiering storage class moves objects to three access tiers: - Frequent Access - for files that are accessed frequently (the STANDARD storage class equivalent).
- Infrequent Access - 45% lower-cost tier for files that have not been accessed for 30 consecutive days (the STANDARD_IA storage class equivalent).
- Archive Instant Access tier - 82% lower-cost tier for files that have not been accessed for 90 consecutive days (the GLACIER_IR storage class equivalent).
You may also activate additional archive tiers to save even more on storage fees for files that are not accessed frequently. - Archive Access - 84% lower-cost tier for files that have not been accessed for at least 90 consecutive days (the GLACIER storage class equivalent).
- Deep Archive Access - 95% lower-cost tier for files that have not been accessed for at least 90 consecutive days (the DEEP_ARCHIVE storage class equivalent).
Please also note that files moved to Archive and Deep Archive access tiers are not accessible immediately, you need to initiate the Restore first and wait from 1-2 minutes to 48 hours (depending on the access tier and retrieval method, please check aws documentation for more details. Additional archive tiers are configured by applying Intelligent Tiering Configuration to the bucket and you may use S3 Browser to perform this task with ease.

Filter
The Add New Intelligent Tiering Configuration dialog - the Filter tab You may define the filter based on the object's prefix and/or by one or multiple object tags. Prefix - identifying one or more files to which the rule applies (e.g. 'logs/'). Empty prefix means all files. Tags - You may define one or multiple tags to apply the rule only to a subset of objects with the specific tag(s). If multiple tags are defined the lifecycle rule applies only to files that have all of the tags specified. Amazon S3 performs a logical AND.
