🌐 What is a CDN?

A CDN (Content Delivery Network) is a network of servers distributed across different locations that helps deliver your website content faster to users based on their geographic location.

📦 How CDN Works

5

Instead of loading your website from a single server:

1. Your content is cached on multiple servers (edge servers) worldwide
2. When a user visits your site
3. The CDN serves content from the nearest server
4. Result → faster loading speed 🚀

⚡ Example

Without CDN:

• User in India → request goes to server in USA → slow

With CDN:

• User in India → content served from nearby (India/Asia) server → fast
