When does S3 Infrequent Access beat Standard?

S3-IA storage costs ~46% less than Standard but charges a retrieval fee per GB. If you access data less than ~1× per month, IA becomes cheaper. The cross-over depends on object size and access frequency.

How does Glacier Instant Retrieval compare?

Glacier Instant Retrieval costs ~68% less than Standard with millisecond retrieval. Ideal for backups accessed rarely (once per quarter). Minimum storage duration is 90 days.

How It Works

Determine the optimal S3 storage class based on retrieval frequency. Calculates monthly cost for S3 Standard, Standard-IA, and Glacier given storage size and access patterns

Each component has a specific meaning:

Retrieval frequency — The retrieval frequency recorded for the patient or scenario being assessed.

Note: Interpret the s3 storage class cross-over result against the clinical thresholds and context described above.

How to Use

Enter the retrieval frequency for the patient or scenario you are assessing. Determine the optimal S3 storage class based on retrieval frequency. Calculates monthly cost for S3 Standard, Standard-IA, and Glacier given storage size and access patterns. Use the s3 storage class cross-over result to inform your clinical assessment.
