If your business primarily supports delivery of large static files hosted on websites
or application, such as
APK game installation files,
RAR application update files, patch files, and audio and video files, you can use Alibaba
Cloud CDN to accelerate the downloads of large files.
Acceleration of large file downloads is suitable for downloading and delivering files that are greater than 20 MB in a variety of formats. We recommend that you use Alibaba Cloud Content Delivery Network (CDN) together with Object Storage Service (OSS) to accelerate the back-to-origin process, which can save up to two-thirds of the back-to-origin bandwidth costs.
- End users cannot download files, or the download speed is low.
- Downloads are easily interrupted when network connections are unstable. Extra resources are consumed to download the resources again.
- Website content is insecure and vulnerable to hijacking attacks.
- File storage costs and performance requirements for the origin server are high.
