What is a CDN? CDN network explained 💥

What is a CDN?

We try to write this article as simply as possible so that the layman understands, professionals will not ask the question "what is a CDN".

A CDN is a network of servers that together ensure that the content of a website can be downloaded from many different places in the world. A server is a computer with a large storage capacity especially suitable for storing internet content, these are mainly used by hosting companies, and of course CDN networks.

How does a CDN work?

By linking a website on a server in Amsterdam to a CDN, it can be downloaded at lightning speed in New York, Tokyo, or Melbourne. The website visitor downloads the content from a server in his neighborhood instead of the original server in Amsterdam.

But ... the fact that the visitor can download your website from up close is not everything. The high-quality servers at the CDN provider are equipped with pure SSD and the fastest possible uplinks so that your content is delivered even faster. But ... there is something else. The cache of your website is regulated by the CDN with the absolute highest quality techniques, no origin server can compete with this. All these facts together ensure that your website opens 2 or 3 times as quickly or even faster in the browser.

The history of the CDN

The first CDN networks were established in the 1990s. Only large companies were able to pay the excessive costs of such a network. This is the reason that long-time hosting companies do not offer standard CDN on servers. Today, however, there are more and more server centers that do. In the old days, everyone really wondered what a CDN was when asked.

But the CDN went through a considerable development and today it is a much better known, cheaper and more common phenomenon. We can say that it was practically unaffordable for the year 2000, very expensive between 2001 and 2010, and only gradually became more affordable for the normal citizen from 2011 onwards. So now available for $ 20 a month with Stackpath...
