How Do CDNs Work?

If you are working in the development area, you are aware that the main problem on the World Wide Web is speed. The swift service becomes a favorite one among clients, and more and more customers will come to it. An easy way to improve performance is to use CDN hosting. The simplicity and convenience of this decision lay in the fact that there is no need to rewrite the database and manually edit the content, but many of us don’t pay enough attention to performance in this area.

However, introducing CDN is not that difficult. Ideally, you set everything up and get a better performance, which in turn leads to an increase in search results, income, and in your popularity.

The idea and its implementation

This tool pulls static files from your server and caches them on its servers. When a browser accesses your resource, this content is loaded via this latter server. This is much faster since they are located all over the world, and the system will choose the closest one.

Actually, this service itself works like a proxy, determining the server closest to the user, which ensures faster and more convenient delivery of data. The abbreviation stands for Content Delivery Network. And there are reliable providers of this service like G-Core Labs that can help you to set everything up.

So, how does the search engine determine when to download files via the outside resource and not from the site’s server? The static file URL is rewritten to point to the needed one. In this case, the browser makes requests to the CDN only, which takes the lion’s share of the load from the server and makes all the processes faster. That’s it! Your clients and customers get the fastest results, and you will grow your satisfied audience.
