Understanding CDN
This page gives a clear walkthrough of CDN, what it means, how to think about it, and why it matters in real life.
What CDN really means
A CDN is a network of servers placed in different geographic locations to help deliver content from a location closer to the end user.
This is especially helpful for web content such as images, videos, JavaScript files, stylesheets, and other assets that people request often.
A CDN caches or serves content from edge locations closer to visitors instead of always making every request travel all the way back to the main origin server.
That can reduce load times, reduce origin server strain, and improve the experience for users in different parts of the world.

CDNs matter because people expect websites and apps to load quickly. A slow experience can hurt usability, conversions, and search performance.
They also help with resilience, traffic spikes, and performance consistency for businesses that serve users in more than one region.

A common misconception is that a CDN replaces web hosting. In reality, the CDN sits in front of or alongside origin infrastructure rather than replacing the need for hosting entirely.
Another misconception is that only huge companies need a CDN. In practice, smaller sites can benefit too, especially when they serve media or want faster global delivery.
Questions people usually have about CDN
