Terminology

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
Cache-Control	protocol	Content Delivery Networks	The HTTP header directing how a response may be cached and for how long, by browsers, proxies and CDNs.
Content Pre-Positioning Proactive Fill, Push CDN, Predictive Caching	pattern	Content Delivery Networks	Pushing predicted-demand content to edge caches during off-peak hours rather than fetching it on first request, converting an unpredictable peak-time origin fetch into a scheduled transfer when capacity is free.
Content Purge Path Takedown Propagation, Cache Purge SLA	practice	Content Delivery Networks	A separate, fast, fail-closed mechanism for removing content from every cache tier, which is what allows long TTLs everywhere else without making removal impossible.
Global Map Serving: Precomputed Tiles at Planet Scale Map Tiles, Tile Pyramid	case-study	Content Delivery Networks	Rendering a map view on demand is impossible at global scale, so the world is precomputed into a pyramid of cacheable tiles addressed by coordinate and zoom.
Origin Shield Parent Cache, Mid-Tier Cache	practice	Content Delivery Networks	An intermediate cache tier between edge locations and origin, so that hundreds of simultaneous edge misses become a handful of origin requests.
Progressive Media Materialisation Lazy Transcoding, On-Demand Rendition	pattern	Content Delivery Networks	Generating only a baseline media rendition on upload and producing higher-quality variants on first demand - trading a slower first view of unpopular content for a large reduction in transcoding and storage cost.
