Which storage solution will meet these requirements?
Move the data objects to S3 Glacier Deep Archive after 30 days.
Move the data objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days.
Move the data objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 30 days.
Move the data objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) immediately.
Explanations:
S3 Glacier Deep Archive is designed for archival storage, with long retrieval times. It does not provide immediate access, which does not meet the requirement of instant accessibility.
S3 Standard-IA is suitable for data that is infrequently accessed but requires immediate availability. It offers the same high durability and resiliency as S3 Standard at a lower cost.
S3 One Zone-IA stores data in a single Availability Zone, which does not meet the high resiliency requirement, as data would be less protected in the event of an AZ failure.
Moving data to S3 One Zone-IA immediately would reduce costs but would not meet the high resiliency requirement, as it provides less redundancy than S3 Standard or S3 Standard-IA.
From my point of view, the answer is:
Move the data objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days.
