A Content Delivery Network (CDN) is a network of servers that distributes static website content—such as images, videos, CSS, and JavaScript files—and delivers them closer to the visitor. This results in faster load times, improved stability, and reliable worldwide access.
How a CDN Works
CDNs operate using so-called edge servers strategically placed around the world. When a user accesses your website, the nearest server delivers the content instead of the main server. This reduces latency, lowers server load, and improves performance.
Benefits of a CDN
- Faster loading times: Content is delivered from the closest server.
- Scalability: Your website remains stable even during traffic spikes.
- Improved security: Many CDNs provide built-in DDoS protection and security features.
- SEO benefits: Google favors fast websites—CDNs can boost your ranking.
- Reduced server load: Many requests are handled by the CDN rather than the main server.
When Does a CDN Make Sense?
A CDN is especially valuable for websites with international audiences, high visitor numbers, or heavy media content. Even smaller websites benefit from faster loading speeds and more stable performance—especially for image- or video-rich content.
