Content Delivery Network

Cache content on global edge nodes so visitors load from the nearest POP — cutting cross-border latency and origin bandwidth costs. Built for websites, apps, and media delivery.

Core capabilities

A CDN fixes latency and bandwidth cost at once

Latency is the easy part: users fetch from the nearest edge, so cross-border requests stop round-tripping to origin. The bandwidth side is more concrete — origin pull is typically a small fraction of total requests, and the edge absorbs the rest.

For cross-border businesses a CDN is less an optimization than a requirement: origin in one region, users on other continents. Skip edge caching and both the experience and the traffic bill fall apart together.

Cache hit ratio decides whether it pays off

A CDN bills cached requests at CDN rates and charges extra for origin fetches. A low hit ratio means you pay the CDN and still carry nearly all your origin traffic — paying twice for one job.

The usual levers: normalize URLs so irrelevant query parameters do not split the cache key, give static assets content-hashed filenames so they can be cached long-term, and split out any part of an API that can be served statically. Landing and detail pages — concentrated traffic, stable content — improve the most.

What should not go through a CDN

Single-use authenticated endpoints, high-frequency polling, and personalized pages that change constantly gain nothing from caching, and can leak one user's data to another if cached by mistake. Give these explicit no-cache rules, or bypass the CDN entirely.
