The Amazon S3 Intelligent-Tiering storage class now automatically includes a new Archive Instant Access tier with cost savings of up to 68% for rarely accessed data that needs millisecond retrieval and high throughput performance. S3 Intelligent-Tiering is the first cloud storage that automatically reduces your storage costs on a granular object level by automatically moving data to the most cost-effective access tier based on access frequency, without performance impact, retrieval fees, or operational overhead. S3 Intelligent-Tiering delivers milliseconds latency and high throughput performance for frequently, infrequently, and now rarely accessed data in the Frequent, Infrequent, and new Archive Instant Access tiers. Now, you can use S3 Intelligent-Tiering as the default storage class for virtually any workload, especially data lakes, data analytics, new applications, and user-generated content.

The Amazon S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective access tier when access patterns change. S3 Intelligent-Tiering automatically stores objects in three access tiers: a Frequent Access tier, an Infrequent Access tier with 40% lower-cost than the Frequent Access tier, and an Archive Instant Access tier with 68% lower-cost than the Infrequent Access tier. For a small monthly monitoring and automation charge per object, S3 Intelligent-Tiering monitors access patterns and moves objects that have not been accessed for 30 consecutive days to the Infrequent Access tier and now, after 90 days of no access, to the new Archive Instant Access tier. For data that does not require immediate retrieval, you can set-up S3 Intelligent-Tiering to monitor and automatically move objects to the optional asynchronous Archive Access tier after 90 days with cost savings of 71%, and after 180 days of no access to the Deep Archive Access tier to realize up to 95% in storage cost savings. 

If you are an S3 Intelligent-Tiering customer, any existing objects that have not been accessed for 90 consecutive days will automatically move to the new Archive Instant Access tier, delivering immediate 68% cost savings for those objects, without any impact on performance. 

There are no retrieval charges in S3 Intelligent-Tiering. If an object in any of the access tiers is accessed, it is automatically moved back to the Frequent Access tier. No additional tiering charges apply when objects are moved between access tiers within the S3 Intelligent-Tiering storage class. If you would like to standardize on S3 Intelligent-Tiering as the default storage class for newly created data, you can modify your applications by specifying INTELLIGENT_TIERING on your S3 PUT API request header. S3 Intelligent-Tiering is designed for 99.9% availability and 99.999999999% durability, and automatically delivers the same low latency and high throughput performance of S3 Standard. You can use AWS Cost Explorer to measure the additional savings from the Archive Instant Access tier.
