Website Acceleration

CDN is perfect to websites that require accelerations, including portals, e-commerce platforms, information apps, and user generated content (UGC). It provides excellent acceleration services for all content under an acceleration domain name, including static and dynamic content. In addition, it supports custom cache policies. Users can set the cache expiration time according to their needs. Files of various formats can be cached, including but not limited to the following formats: .zip, .exe, .wmv, .gif, .png, .bmp, .wma, .rar, .jpeg, and .jpg.

Download Acceleration

CDN also applies to download tools, game clients, app stores, and websites that provide download services based on HTTP or HTTPS. An increasing number of new services, such as apps and mobile games, require updating of their client software in real time. Conventional download services need to support more files of larger sizes. If origin servers process all these requests, the servers and the network will bear great traffic, degrading download experience. With CDN download acceleration, content to be downloaded is distributed to edge nodes in different locations, relieving the origin servers from heavy traffic stress and ensuring high-speed download experience.

VOD Acceleration

For customers providing on-demand video/audio services, CDN is a must. Such on-demand services include online education websites, online video sharing websites, Internet video-on-demand platforms, and video/audio on-demand apps. Conventional video/audio on-demand services cause heavy load on servers and consume huge bandwidth resources. End users' experience is thereby compromised with low-speed services. However, CDN provides fast, reliable, and secure acceleration for such services by delivering the contents to all CDN nodes, so that users can obtain the contents from the nearest node anywhere and anytime.

Whole Site Acceleration

For websites that consist of both dynamic and static content and have many dynamic resource requests like those for .asp, .jsp and .php files, CDN is a good option. CDN's whole site acceleration include dynamic acceleration and static acceleration. Static content can be accessed from the nearest node, while dynamic content is retrieved from the origin server though the optimal route. As CDN contributes to whole site acceleration and real-time optimization, dynamic pages can be loaded more quickly, bypassing congested routes, and users are more likely to successfully get the content they want.
