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


The Image and Small File workload type is suitable for accelerating the distribution of a large number of static resources on websites and applications. Examples of the websites and applications include web portals, e-commerce websites, news websites and applications, and gaming and other entertainment websites. You can separate static and dynamic content. To accelerate the distribution of static content, such as images, small CSS files, and small JavaScript files, we recommend that you 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.Image and small file distribution

Issues resolved

  • Websites respond slowly because they contain a large number of small files.
  • The web page load speed and the quality of web services differ across regions. If you send requests for cross-region data access, the websites may respond slowly.
  • During the promotion period, origin servers are more likely to break down due to heavy traffic and high concurrency. The services may become unavailable.
  • Images cannot be compressed or optimized to meet client requirements for image formats and resolution.
