Product Details

The Alibaba Cloud CDN is built to automatically handle spikes in traffic, reduce load speed on your origin site and support storage capacity of up to 1.5 petabytes.

With its low latency and high data transfer rate, the Alibaba Cloud CDN directs user requests to the most suitable node based on network congestion to retrieve content in the most efficient manner. The CDN has a high performance cache system built with powerful clusters of servers to maximize throughput. The CDN relies on an intelligent object heat algorithm and hierarchical ‘hot’ cache resources for precise resource acceleration.


Fast Content Delivery

Improves availability of CDN servers or nodes with high-speed read/write storage using SSDs. Accelerates content distribution with page optimization and smart compression technologies.

  • Page optimization removes spaces, line breaks, TABs, annotations, and other redundant page content to reduce page size.

  • Smart compression reduces size of the content and accelerates content distribution.

Reduces response time by collapsing multiple JavaScript/CSS files into a single request.

Advanced Scheduling

  • Reduces complexity by supporting millions of domain names with a single machine.

  • Ensures high availability with multi-level scheduling policies.

  • Simple and easy to use. Coordinates security systems, refresh systems and content management systems using multi-system interaction techniques.

  • Enhances user experience with real-time data scheduling option and advanced traffic predictions.


  • High-speed audio and video downloads using acceleration feature for on-demand and live streaming media.

  • Quick and easy integrated solution which includes media storage, slicing and transcoding and access authentication.

  • Smooth playback experience delivered through on-demand audio and video incremental service.

  • Easy deployment with support for MP4 and FLV video formats.
