I. INFORMATION

CDN (Content Delivery Network) is a digital content delivery network service consisting of many storage servers located in different geographical locations, working together to deliver images, videos, live streams, CSS, Javascript, File downloads,... to end users. CDN helps customers access data as quickly as possible from the web server closest to them instead of having to access the web server at the data center.

CDN helps digital content service providers improve quality and increase access response.
