S3 Intelligent-Tiering now supports automatic data archiving to further optimize storage costs when data access patterns change and subsets of objects become rarely accessed over long periods of time. S3 Intelligent-Tiering delivers milliseconds latency and high throughput performance for frequently accessed data and now the lowest storage costs in the cloud when data is not accessed for long periods. S3 Intelligent-Tiering is the only cloud storage class that delivers automatic cost savings by moving objects between four access tiers when access patterns change. There are two low-latency access tiers optimized for frequent and infrequent access, and two new archive access tiers for asynchronous access that are optimized for rare access at low costs. 

With the addition of automatic data archiving, S3 Intelligent-Tiering can further optimize storage costs when access patterns change, without any analysis, operational overhead, or retrieval fees. For a small monthly object monitoring and automation fee, S3 Intelligent-Tiering monitors access patterns and automatically moves objects that have not been accessed for 30 con-secutive days from the frequent access tier to the infrequent access tier. Once you have activated one or both of the ar-chive access tiers, which are designed for asynchronous access, S3 Intelligent-Tiering will automatically move objects that haven’t been accessed for 90 days to the archive access tier, and after 180 days to the deep archive access tier. Any time an object in the archive access tier or deep archive access tier is accessed, the object is moved to the frequent access tier, in as little as a few hours.

S3 Intelligent-Tiering is designed for 99.9% availability and 99.999999999% durability. Like other Amazon S3 storage classes, S3 Intelligent-Tiering supports features like S3 Inventory to verify the access tier of objects, and S3 Replication to replicate data to any Amazon Web Services China China Region. There are no retrieval fees when using the S3 Intelligent-Tiering storage class, and no addi-tional tiering fees when objects are moved between access tiers. It is the ideal storage class for datasets with unknown or unpredictable changing access patterns. 

You can activate one or both of the S3 Intelligent-Tiering archive access tiers using the Amazon S3 API, CLI, or with a few sim-ple clicks in the S3 management console. S3 Intelligent-Tiering, and the new archive access tiers, is available today in all Amazon Web Services China Regions, including the Amazon Web Services China China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China China (Ningxia) Region, operated by NWCD.
