If your business involves the distribution of small static web pages or application files, such as images, HTML files, flash files, CSS files, and JavaScript files, you can select the Image and Small File business type to accelerate the distribution.


The Image and Small File business type is suitable for accelerating the distribution of large numbers of static resources on websites or applications, such as Web portals, e-commerce websites, news websites and apps, and gaming and other entertainment websites. You can separate static and dynamic content on a website. To accelerate the distribution of static content, such as images and small CSS and JavaScript files, use Alibaba Cloud CDN. To accelerate resource loading and distribution of images and short videos on websites, we recommend that you use Alibaba Cloud CDN together with Object Storage Service (OSS).

The following figure shows a typical architecture where Alibaba Cloud CDN is used to accelerate the distribution of images and small files.Architecture diagram

Issues resolved

  • Websites respond slowly because they contain a large number of small files.
  • The web page loading speed and the quality of media feeds retrieved from the websites differ across regions. This may negatively affect the user experience.
  • During the promotion period, origin servers are more likely to break down due to heavy traffic.
  • Images cannot be compressed or optimized to fit client requirements.
