CONTENT DELIVERY NETWORK (CDN)

CDN is a network of distributed servers strategically placed around the world, working together to deliver web content, such as images, videos, and other resources, to users from a server that is geographically closer to them.

Here's how CDN works:

1. User Request: You type a website's URL in your browser.
2. CDN Routing: Request goes to the nearest CDN server.
3. Content Check: CDN checks if the content is cached.
4. Cached Content: Cached content is sent if available.
5. Retrieve if Needed: If not cached, CDN fetches from the original server.
6. Balancing and Speed: CDN balances traffic, reducing latency.
7. Quick Display: Content loads faster in your browser.
8. Enhanced Experience: CDN ensures smoother browsing.

Examples - Cloudflare, Amazon CloudFront
