AWS S3 Offers a Storage Option for Rarely Accessed Data Amazon Web Services (AWS), recently announced improvements to its Simple Storage Service (S3). These include an expansion of its Intelligent Tiering option to store archival data. AWS launched S3 Intelligent-Tiering in March 2012 to provide S3 users with a more cost-effective storage option for data that has unpredictable access requirements. There are two data tiers within the S3 Intelligent-Tiering option. One for data that is accessed frequently and another for data that is accessed less often. The service automatically moves data objects between tiers based on how frequently users request access. If an object isn’t accessed in 30 days, it is moved to the infrequent accessibility tier. Once it is accessed again, it is moved back to the frequent tier. This is a process that optimizes storage costs for data that is only occasionally, irregularly, or both. AWS announced this week an expansion to S3 Intelligent-Tiering. Archive Access and Deep Archive Access are now available to access data that is rarely accessed. The first tier is for data that hasn’t been accessed in the last 90 days and the second for data that hasn’t been accessed within 180 days. S3 Intelligent-Tiering can move data from one tier of the hierarchy to another as needed. Marcia Villalba is an AWS senior developer advocate and wrote a blog post about the cost benefits of S3 Intelligent-Tiering. You pay monthly storage, request, and data transfer. Intelligent-Tiering allows you to pay a small per-object fee each month for automation and monitoring. S3 Intelligent-Tiering does not charge a retrieval fee or charge for data movement between tiers. Objects in Frequent Access tier get billed at S3 Standard’s rate, while objects in Infrequent Access tier objects are billed at S3 Standard Infrequent Access. Objects stored in Archive Access tier objects are billed the same as S3 Glacier, and objects in Deep Archive access Tier objects are billed the same as S3 Deep Glacier. AWS also announced some other S3-related enhancements last week.
