Study Notes
- CDN, or content delivery network, was developed in the late 90s to speed up the delivery of static HTML content globally.
- CDNs bring content closer to users by deploying servers at hundreds of locations worldwide called Points of Presence (PoPs).
- Different CDNs use technologies like DNS-based routing and Anycast to direct user requests to the closest PoP for faster content delivery.
- Edge servers within PoPs act as reverse proxies with content caches, reducing load on origin servers by serving cached content.
- Modern CDNs not only improve performance but also enhance security by providing effective DDoS protection and increase availability by distributing content across multiple PoPs.
