A Content Delivery Network or CDN helps speeding up the access to a website by shortening the virtual distance between the people visiting a site and the server delivering its content. In most cases, a site’s components and its static data are distributed and saved on servers around the globe. That way, anyone accessing the site from anywhere in the world is able to load content from a local server instead of having to wait for it to be provided by the original server. This can have a positive impact on load times, as it decreases the strain on hosting server as well as saves bandwidth costs for users.
