Data may be unused for months and then accessed suddenly.
Reduce manual class changes while keeping objects immediately retrievable.
Which storage class is most appropriate?
Consider S3 Intelligent-Tiering to move objects automatically according to observed access.
Detailed explanation
Infrequently accessed objects continue incurring the frequent-access storage price.
