Which storage class should be used for data that is infrequently accessed?

The S3 Standard-IA (Infrequent Access) storage class is specifically designed for data that is accessed less frequently but still requires rapid access when needed. This option provides a lower storage cost compared to the S3 Standard class while also ensuring that data retrieval times are quick, making it ideal for infrequently accessed data.

S3 Standard-IA is well-suited for scenarios where you have large amounts of data that do not need to be accessed every day, but you still want it to be readily available when required, such as backups or long-term storage of data that is not actively used.

In terms of cost efficiency, S3 Standard-IA also includes a retrieval fee for when data is accessed, which is acceptable for datasets that are not frequently accessed but still need to be available quickly without the longer delay associated with more archiving-focused classes like S3 Glacier.

Other options, such as S3 Glacier, are intended for archival data with retrieval times that can range from minutes to hours, making them unsuitable for data that requires faster access. Meanwhile, S3 Standard is optimized for frequently accessed data, and S3 Intelligent-Tiering is designed for datasets where access patterns change over time. Thus, when focusing on infrequently accessed data
