2205 terms, tools, patterns and metrics an architect is expected to use precisely. Each one gets a short explanation of what it is, and — where it matters — what it is commonly confused with. Search filters as you type; the column headers sort.

Term	Kind	Topic	What it is
Chunk-Level Deduplication Content-Defined Chunking, Sub-File Deduplication	pattern	Storage Costs	Splitting files into content-addressed pieces at boundaries chosen by the data itself, so repeated rewrites of a large artifact store only the bytes that changed rather than a new full copy.
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.
Storage Lifecycle Policy	practice	Storage Costs	Automated rules that move objects between storage classes as they age, matching cost to the declining probability that data will be read.
