Website Acceleration

CDN is perfect for websites that require acceleration, including portals, e-commerce platforms, news apps, and apps used for user generated content (UGC). It provides excellent acceleration for all content under an acceleration domain name, static and dynamic content alike. In addition, it supports custom cache policies. Users can set the cache expiration time as needed. The files that can be cached include but are not limited to .zip, .exe, .wmv, .gif, .png, .bmp, .wma, .rar, .jpeg, and .jpg.

Download Acceleration

CDN is useful for download clients, 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 software updates in real time. Conventional download services need to provide even more and larger downloads. If origin servers have to handle all of these requests directly, it places tremendous strain on these servers and results in a significant bottleneck. With CDN download acceleration, content to be downloaded is distributed to edge nodes, easing the pressure on origin servers and ensuring high-speed downloads.

VOD Acceleration

For customers providing on-demand audiovisual services, CDN is a must. Such on-demand services include online education websites, online video sharing websites, Internet video-on-demand platforms, and on-demand audiovisual apps. Conventional on-demand audiovisual content puts significant load on the servers and consumes an enormous amount of bandwidth. When this happens, user experience is compromised for low-speed services. CDN ensures fast, reliable, secure acceleration for such services by delivering content to all CDN nodes. Users are then able to obtain that content from nearby nodes anywhere and anytime.

Live Streaming Acceleration

For customers that have their own video processing centers, CDN accelerates live streams.

Whole Site Acceleration

CDN is a good option for websites that consist of both dynamic and static content and for sites that involve a large number of ASP, JSP, or PHP requests. CDN's whole site acceleration accelerates both dynamic and static content. Static content can be accessed from the nearby node, while dynamic content is retrieved from the origin server through the optimal route. As CDN contributes to whole site acceleration and real-time optimization, dynamic pages can be loaded more quickly. Site congestion is reduced and site access is made more reliable.
