CDN (Content Delivery Network)

A CDN is a distributed server system that delivers web content (images, videos, scripts, HTML, etc.) quickly and efficiently to users based on their geographical location.

CDNs help reduce latency, improve website performance, and enhance security by caching content closer to end users.

CDN

🔹 How a CDN Works

1️⃣ User Requests Content → A visitor accesses a website (e.g., loading an image or video). 2️⃣ CDN Routes Request to Nearest Server → Instead of retrieving data from the origin server (which may be far away), the CDN serves cached content from a nearby edge server. 3️⃣ Faster Load Time → Since data travels a shorter distance, website speed improves and reduces server load.

📌 Example: A user in New York visits a website hosted in Singapore. Without a CDN, the data would travel long distances, causing slow loading. With a CDN, the content is delivered from a CDN server in New York, making the site load much faster.


🔹 Benefits of Using a CDN
