Overview
Alibaba Cloud CDN, operated by Alibaba Cloud, is a global content delivery network with over 1,200 points of presence (POPs) across more than 70 countries. It specializes in accelerating content delivery for websites, video streaming, and large-scale downloads, particularly in the Asia-Pacific (APAC) region and China. The service supports a range of industries, including e-commerce, gaming, and media, with a strong focus on compliance with China’s regulatory requirements. Customers include enterprises and developers needing low-latency delivery in APAC markets. The platform integrates with other Alibaba Cloud services like Elastic Compute Service (ECS) and Object Storage Service (OSS) for streamlined content hosting.
Network & Architecture
Alibaba Cloud CDN operates over 1,200 POPs globally, with a significant presence in APAC, including China, where it holds a Ministry of Industry and Information Technology (MIIT) license for compliance. The network leverages extensive peering with local ISPs in China to ensure low-latency delivery. It uses tiered caching and origin shield to reduce origin server load. The service is optimized for high-traffic scenarios like e-commerce events (e.g., Singles Day), but its coverage in Africa and Latin America is less extensive compared to North America and EMEA.

Pricing
Alibaba Cloud CDN uses a pay-as-you-go (PAYG) model with pricing based on traffic volume and region. A free trial is available, offering up to 12 months of usage for select services like Elastic Compute Service, which integrates with CDN. Per-GB pricing varies by region, with China typically higher due to regulatory compliance costs. Detailed pricing is available at https://www.alibabacloud.com/product/cdn/pricing.
Integrations & DevEx
The service supports Terraform for infrastructure-as-code, enabling automated configuration of CDN domains. SDKs are available for multiple languages, facilitating integration with CI/CD pipelines. Real-time logs and analytics are accessible via the console or API, with log push capabilities for external storage. A self-service diagnostics tool helps troubleshoot issues like page loading failures. Domain transfer tools simplify migrations across Alibaba Cloud accounts.
