A CDN is essentially a network of geographically dispersed servers. Each CDN node (also called Edge Servers) caches the static content of a site like the images, CSS/JS files and other structural components. The majority of an end-user's page load time is spent on retrieving this content, and so it makes sense to provide these "building blocks" of a site in as many server nodes as possible, distributed throughout the world.
When a user requests your site, the node closest in proximity to user will deliver the static content, ensuring the shortest distance for the data to travel (reduced latency), therefore providing the fastest site experience.
The number one reason for using a CDN is to improve your user's experience in terms of speed, and as we know - speed matters! Ensuring a consistent experience for all your users is important.
Using the CDN is essential if you want to reach users around the world, either for downloading files, or deploying websites and web applications.
If international targets matter to you or your customers, the CDN has the advantage of speeding up page loading times (response time), improving user comfort, securing your data, improving SEO and reducing your bandwidth costs in each target country.
Your ROI (Return On Investment) can be very short from the moment you or your customers stream any contents internationally.
