About cdn Technology

The full name of CDN is Content Delivery Network, that is, content delivery network. Its purpose is to publish the content of the website to the "edge" of the network closest to the user by adding a new network architecture to the existing Internet, so that users can get the content they need nearby and improve the response speed of users visiting the website.

The user enters the domain name of the website to be visited in his browser, the browser requests the resolution of the domain name from the local DNS, and the local DNS sends the request to the main DNS of the website, which determines the most appropriate CDN node according to a series of policies, and sends the resolution result (IP address) to the user, who requests the content of the corresponding website from the given CDN node.

About Virtual Host

Virtual host is a method to implement multi-domain services on a single host, which can run multiple websites or services. A virtual host is also called "website space", which divides a physical server running on the Internet into multiple "virtual" servers.

Virtual host technology has greatly promoted the application and popularization of network technology. The technology is the cost-saving technology of server hardware adopted by the Internet server, which is mainly applied to many services such as HTTP,FTP,EMAIL. One or all of the service contents of a server are logically divided into multiple service units, which are externally represented as multiple servers, thus making full use of server hardware resources.
