Glossary

An edge network is a geographically distributed network of servers, often called points of presence, located close to the users making requests. The "edge" refers to the outer boundary of the network, nearest to those users, as opposed to a central origin server.

By handling requests near where they originate, an edge network reduces latency and spreads load. Edge networks are commonly used to cache and serve static assets, as with a CDN, and increasingly also to run code such as redirects, rewrites, personalization or serverless functions close to the user.
