A Content Delivery Network (CDN) is a system of distributed servers that work together to deliver web content—like images, videos, stylesheets, and JavaScript files—to users based on their geographic location. Instead of relying on a single, central server, a CDN stores cached copies of your site's content on servers around the world. When a visitor requests a page, the CDN serves it from the server closest to them, dramatically speeding up load times.

For your hosting, using a CDN provides several key benefits:

• Faster Loading Speeds: Reduced distance between the user and the content means quicker delivery.
• Improved Reliability & Uptime: If one server has an issue, traffic is automatically routed to another.
• Enhanced Security: Many CDNs offer DDoS protection and other security features to shield your site.
• Reduced Bandwidth Costs: By caching content, CDNs decrease the load on your origin server, saving resources.

In essence, a CDN is not a replacement for web hosting, but a powerful complement that makes your site faster, more secure, and more resilient for a global audience. It's a crucial tool for any website owner looking to provide an optimal user experience.
