What is a CDN? How Cloudflare Boosts Speed and Protects Your Origin Server
A Content Delivery Network (CDN) is a geographically distributed group of edge servers that cache static assets near end-users.
1. How Edge Caching Works
When a visitor in Bengaluru requests your website hosted in Delhi, the CDN serves images, CSS, and JS files from its local Bengaluru edge point of presence (PoP), cutting latency to single-digit milliseconds.
2. Origin IP Shielding & DDoS Mitigation
Cloudflare proxies all incoming traffic through its massive Anycast network. Malicious scrapers and volumetric DDoS attacks are scrubbed at the edge, shielding your origin web host from crashing.
