How CDN works

The classical set-up is that you have a website at one location (one server) in the world. If all your visitors are near to that location then it is usually a well working set-up because all your visitors are being served at a short distance from your server.

Content Delivery Network (CDN) Architecture

Content Delivery Network (CDN) Architecture

Without CDN

The classical set-up is that you have a website at one location (one server) in the world. If all your visitors are near to that location then it is usually a well working set-up because all your visitors are being served at a short distance from your server.

With CDN

Your websites’ static content (images, CSS, JavaScripts, etc.) which is large (compared to HTML files) and thus suffers high latency the most, will be distributed (cached or mirrored) to more than 50 data centers (PoPs) around the world. The distance between your website content and your website’s visitors will be significantly reduced resulting in a game-changing customer experience and a higher Google ranking.

Moreover, all our CDN edge servers are connected to the fastest and most robust networks of the Internet and they are equipped exclusively with the fastest SSD drives which will increase your online performance even more.

Knowledge base
What is Pay As You Go CDN?

A Pay As You Go CDN provider is a CDN provider for which $ credit is purchased in advance of CDN services usage. The purchased credit is used to pay for CDN services usage at the moment when the CDN services are accessed. If there is no available credit then the corresponding account and its resources are suspended by the CDN provider. Note that the term Pay As You Go (PAYG) originally comes from prepaid mobile phone services.

How to set up CDN?

For majority of website solutions such as Wordpress, Magento, Discourse, etc. you just need to follow few simple steps. Please take a look at our CDN integrations.

In general to use a CDN you need to change source attribute of your static content (images, CSS, JavaScripts, videos, etc.) to point to a CDN URL. That's all.

How is content uploaded to CDN?

Your content is automatically pulled from your website (or your CDNsun storage) by our CDN edge servers at the moment when it is requested by your visitors.

When your visitor requests your CDN content, then the content is automatically pulled from your server (if it is not already cached), then it is served (by a CDN edge server) to the visitor, and then it is cached (stored) on the edge server, and all subsequent requests to that edge server are served from its CDN cache.

Moreover, you can immediately prefetch your content to all CDN edge servers using our dashboard or REST API.
