S3 Intelligent Tiering is a storage class that has multiple tiers embedded within it, each with its own access latencies and costs – it is an automated service that monitors your data access behavior and then moves your data on a per-object basis to the appropriate level of tier within the S3 Intelligent Tiering storage class. If your object has not been accessed for 30 consecutive days it will automatically move to the infrequent access tier within S3 Intelligent Tiering, and if the object is not accessed for 90 consecutive days it will automatically move the object to the Archive Access tier and then after 190 consecutive days to the Deep Archive access tier. If an object is moved to the archive tier, the retrieval can take 3 to 5 hours and if it is in the deep archive tier it can take 12 hours. and if it is then subsequently accessed it will move it into the frequently accessed storage class.
