CDN (Content Delivery Network)
Also known as: CDN / Content Delivery Network / コンテンツデリバリーネットワーク
A network of globally distributed edge servers that cache and deliver content to users from the nearest location. Cloudflare, AWS CloudFront, and Fastly are leading providers, reducing latency for static files, images, and video while reducing origin load.
Overview
A CDN caches origin server content at edge PoPs worldwide, delivering it from the node closest to each user. This simultaneously improves response speed and reduces origin server load.
Web Performance
Next.js and Vercel leverage CDN caching through SSG by default, directly improving Core Web Vitals scores. See website speed optimization guide for details.
