Final answer:
The minimum storage size differences are tied to the storage duration charges for Amazon S3 IA, Glacier, and Glacier Deep Archive. S3 IA has a minimum charge for 30 days, Glacier for 90 days, and Glacier Deep Archive for 180 days.
Step-by-step explanation:
The question pertains to the minimum storage size difference between Amazon S3 Standard-Infrequent Access (S3 IA), Amazon S3 Glacier, and Amazon S3 Glacier Deep Archive, which are all storage classes offered by AWS for different use cases. Amazon S3 IA is designed for data that is accessed less frequently but requires rapid access when needed. Amazon Glacier is meant for archiving data that is accessed infrequently where retrieval times of several hours are acceptable. Finally, Amazon S3 Glacier Deep Archive is for data that may be accessed once or twice in a year and offers the lowest storage cost.
The minimum storage charge for S3 IA is for 30 days. For S3 Glacier, AWS charges for a minimum of 90 days of storage, even if you delete the data before that. And for S3 Glacier Deep Archive, the minimum storage duration charge is for 180 days. This difference in minimum storage duration impacts the cost-effectiveness of each storage option depending on the expected frequency of access and the retention period required by the user.
