Understanding CDN (Content Delivery Network) in E-commerce

Quick Definition

A Content Delivery Network (CDN) is a geographically distributed network of servers that cache and deliver web content from locations closest to end-users. By reducing physical distance between server and user, CDNs dramatically improve website loading speeds, enhance user experience, and provide robust protection against traffic spikes and DDoS attacks.
