Term	Kind	Topic	What it is
Minimum Storage Duration Charge Early Deletion Fee, Minimum Billable Duration	concept	Storage Costs	The contractual floor on how long an object in a cheaper storage class is billed for, which converts deletions and extra lifecycle hops inside that window into charges rather than savings.
Retrieval-Cost Trap Archival Access Cost, Cold Tier Scan Penalty	concept	Storage Costs	The failure where moving data to an archival tier saves storage cost and a scanning access pattern then spends more on retrieval than the tiering saved.
Storage Costs	concept	Storage Costs	Storage is cheap per gigabyte and expensive in aggregate — controlled by retention and tiering rather than by unit price.
