Introduction
Content Delivery Networks (CDNs) are distributed networks of servers that deliver web content—such as images, videos, scripts, and web pages—to users based on their geographic location. Instead of loading content from a single origin server, CDNs cache and serve it from the nearest edge location, reducing latency and improving performance.
In simple terms, a CDN makes your website or app faster, more reliable, and scalable by bringing content closer to users.
As digital experiences become richer and more global, CDNs are no longer optional. They now play a critical role in performance optimization, security, and availability, especially for high-traffic websites, SaaS platforms, and streaming services.
