A Content Delivery Network (CDN) enhances website performance by distributing content across a network of servers strategically located around the globe. This geographical distribution enables faster content delivery to users by reducing the physical distance data must travel, thus minimizing latency and loading times. CDNs improve resilience against traffic spikes and security threats, such as DDoS attacks, by caching content and providing an additional layer of protection. By offloading traffic from the origin server, CDNs ensure a more reliable and efficient user experience, supporting robust performance for dynamic and static websites alike.
