Terminology

2185 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
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.
Cost-Weighted Rate Limiting Compute Units, Weighted Quotas	pattern	API Gateways	Limiting callers by the resources their requests consume rather than by request count, because on any API where request cost varies by orders of magnitude, counting requests protects nothing.
Gateway Offloading	pattern	API Gateways	Moving cross-cutting concerns — TLS termination, authentication, rate limiting, compression, logging — from every service into the gateway.
Origin Shield Shield Tier, Mid-Tier Cache, Request Collapsing Tier	pattern	Reverse Proxies	An intermediate caching tier between edge caches and the origin that collapses many simultaneous misses into a single origin fetch - which is what makes multi-CDN and live streaming survivable for the origin.
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.
Reverse Proxy	pattern	Networking	A server that receives client requests on behalf of one or more backends, forwarding them and returning the response.
Reverse Proxy in Practice	pattern	Reverse Proxies	A server that sits in front of origins and terminates, caches, routes and protects — the cheapest place to solve several problems at once.
Traffic Splitting	pattern	Service Mesh Networking	Directing a defined percentage or subset of requests to a different version of a service, configured at the routing layer rather than in application code.
WebSocket Backplane	pattern	WebSockets & Realtime	A shared publish/subscribe layer letting a message published on one server reach clients connected to a different server.
