dev.sec-s3-lifecycle Calculator
Calculates S3 storage cost savings from lifecycle transitions (Standard → Infrequent Access → Glacier) based on access patterns in a security engineering and compliance context. S3 Intelligent-Tiering automatically moves objects between access tiers — objects not accessed for 30 days move to IA (40% cheaper); 90 days to Archive (68% cheaper).
Inputs
Tb
Reference formula or conversion factor shown for context.
Std
Reference formula or conversion factor shown for context.
Ia
Reference formula or conversion factor shown for context.
Results
S3 Standard
Sample size or count used in the calculation.
S3-IA
Amazon S3 Infrequent Access -- a lower-cost storage class for data accessed less than once per month. Retrieval fee applies; no minimum storage duration discount for under 30 days.
Glacier
Amazon S3 Glacier -- archival storage at very low cost. Retrieval takes minutes to hours. Use for compliance archives or rarely accessed backups.
total
The combined total across all inputs and components.
