What is a CDN_第1张图片
​A content delivery network (CDN) is a collection of global servers that caches and delivers content such as images, videos and Javascript files. When a user requests a web page, for instance, content on that page is delivered by the closest edge server rather than the origin server, thereby decreasing page load time.
