A company stores medical reports and images in Amazon S3 Standard storage.

The medical reports needreal-time accesseven though they are read only about once a year, which matchesS3 Glacier Instant Retrieval. AWS documents that objects in Glacier Instant Retrieval are immediately available with GET, making it the right archival class when access is infrequent but still must be immediate. The medical images are rarely accessed and can tolerate slower retrieval, soS3 Glacier Deep Archiveis the lowest-cost long-term archival choice. AWS recommends Deep Archive for long-lived data that is accessed less than once a year and can wait hours to days for restore completion. That combination optimizes cost while still meeting the very different retrieval requirements for reports and images. (AWS Documentation)
