Content Delivery Networks (CDNs)
Understand how CDNs work and how to leverage them to deliver content faster to users worldwide.
Intro to Content Delivery Networks
Welcome! Today we'll explore Content Delivery Networks (CDNs), a powerful tool for speeding up your website globally.
A CDN is a network of servers distributed geographically. Its main job is to deliver web content to users faster by placing it closer to them.
How CDNs Work: The Basics
Imagine your website's content is stored on a single server (the origin server). If a user in another country requests your site, the data has to travel a long distance.
A CDN solves this by having many servers, called edge servers or Points of Presence (PoPs), located around the world. These edge servers cache copies of your content.
