Overview
Alibaba Cloud CDN accelerates websites, downloads and media delivery. It integrates with services such as Object Storage Service (OSS).
Its programmable CDN configuration is distinct from related ESA, Edge Node Service and ApsaraVideo products; compare the exact product you intend to deploy.
DCDN stopped accepting new customer activations on March 12, 2026. Check ESA for a new dynamic-acceleration deployment. This restriction concerns the separate DCDN product; it does not announce retirement of Alibaba Cloud CDN.
Network
- The documented footprint is 3,200+ CDN PoPs, including 2,300+ in mainland China and 900+ outside. The published aggregate capacity is 180 Tbps.
- The node-distribution table names selected cities and broader countries or provinces. These are not equivalent to individual facility locations.
- Billing regions and routing determine which footprint applies to your audience; test the actual user networks.
Published named cities outside mainland China, shown at approximate city centers. Country-only entries and individual facilities are not plotted. This is a subset of the network.

✓ Supported · Partial: limited or separate-product support · ✗ Not supported · Not listed: unconfirmed. Some features need a separate product or plan.
- Delivery: HTTP/3, TLS 1.3, signed URLs, cache rules, image editing and byte-range video access.
- Configuration: EdgeScript changes CDN request workflows; ESA functions and general compute services are separate products.
- Security: CDN can integrate with Anti-DDoS. Existing CDN WAF deployments have a different lifecycle from new ESA protection; CDN WAF no longer accepts new activation.
- Monitoring: real-time metrics and offline or real-time logs. Log delivery and some secure-request protocols have separate fees.
The CDN delivers prepared media. Ask separately how live ingest, packaging and DRM will be supplied.
Pricing
- Choose pay-as-you-go or prepaid resource plans; excess resource-plan usage falls back to PAYG.
- Basic delivery uses either data transfer or peak bandwidth. Region and billing cycle affect the estimate.
- Static HTTPS/QUIC requests and real-time logs have separate optional fees. Origin traffic is not charged by CDN, but the origin may charge outbound transfer.
- CDN and DCDN are billed separately.
Developer tools
- OpenAPI and SDKs support domain configuration, cache refresh and reporting.
- Terraform supports infrastructure-as-code management.
- EdgeScript customizes supported CDN workflows; it is distinct from a general serverless runtime.
When it fits
- Websites, software downloads and prepared media using Alibaba Cloud or external origins.
- Teams using OSS and CDN APIs or Terraform for delivery automation.
- Mainland-China delivery where the domain and deployment meet the applicable onboarding requirements.
Before you choose
- Your application needs a capability available only in a different Alibaba Cloud product.
- Your deployment assumes global and mainland-China delivery have identical requirements or prices.
- Regional performance has not been tested from your audience networks.
