If your business involves the distribution of large static web pages or application
files, such as
.apk game installation files,
.rar application update files, patch files, and audio and video files, you can select
the Large File Download business type to accelerate the distribution.
The Large File Download business type is suitable for accelerating the downloading and distribution of files that are greater than 20 MB. We recommend that you use Alibaba Cloud CDN together with Object Storage Service (OSS) to accelerate the back-to-origin process, which can reduce up to two-thirds of the back-to-origin bandwidth costs.
- End users cannot download files, or the download speed is too low.
- Downloads are easily interrupted when the network environment is unstable. Repeated downloads of the same file consume additional resources each time.
- Website content is insecure and easily hijacked.
- File storage costs are too high, and performance requirements for the origin server are highly demanding.
