CDN (Content Delivery Network) (شبكة توزيع المحتوى)

A Content Delivery Network (CDN) is a distributed network of servers that caches and serves website content from locations close to each visitor. It dramatically speeds up page loads, reduces origin server load, and improves reliability worldwide.

In detail

When a user requests a page, every image, script, and stylesheet travels across the internet. A CDN stores copies of that static content on edge servers around the globe, so a visitor is served from the nearest location instead of a distant origin. This cuts latency, handles traffic spikes by absorbing load, and keeps sites available even if the origin has issues. CDNs also provide DDoS protection, caching rules, and performance optimizations like compression and image resizing. For any site serving a global or regional audience, a CDN is one of the easiest and biggest speed wins.

Practical example

After adding a CDN, the store's images load from a server in the visitor's own region, halving page-load time.
