Cache hit ratio is the share of requests a CDN or cache answers from stored copies instead of the origin, a key measure of content delivery…
A CDN is a geographically distributed network of caching servers that delivers web content from locations close to users to cut latency and origin load.
An edge cache is a cache on CDN servers near users that stores copies of web content, answering requests locally instead of contacting the origin.
An edge network is a distributed set of servers placed close to users that caches, secures and computes on traffic before it reaches the origin.
An origin server is the authoritative server that holds the original content a CDN or proxy cache fetches, stores and delivers to users.
An origin shield is a designated CDN cache layer between edge locations and the origin server that collapses cache misses and reduces origin load.
A point of presence is a physical site where a CDN or network places servers and interconnects with other networks to serve nearby users.
