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.
Imperva provides a cloud-based CDN integrated with its Web Application and API Protection (WAAP) platform, focusing on security and performance. The service includes content caching, load balancing, and global Points of Presence (PoPs) to deliver low-latency web experiences. It offers robust DDoS protection, a Web Application Firewall (WAF), and bot mitigation, making it suitable for enterprises prioritizing security. Imperva serves industries like finance, healthcare, and e-commerce, with clients such as Mediolanum and Vodafone. The company, founded in 2002 and headquartered in San Mateo, California, was acquired by Thales in 2019. Its CDN is part of a broader cybersecurity suite, emphasizing secure content delivery.
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.
Imperva operates a global network with PoPs in North America, EMEA, APAC, and LATAM, including data centers in cities like Tokyo, New Delhi, and Miami. The exact number of PoPs is not publicly disclosed, but the network supports traffic rerouting during maintenance to ensure availability. It uses machine learning for dynamic caching and integrates with major peering partners for optimized routing. Regional strengths include North America and EMEA, with ongoing expansions in APAC and LATAM. Maintenance schedules, such as the August 2025 migrations in Hong Kong and Paris, ensure minimal disruption for Cloud WAF customers. Limitations include less transparency on PoP counts compared to competitors like Cloudflare.

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.
Imperva uses a pay-as-you-go (PAYG) model with enterprise-focused pricing, typically requiring custom quotes. No free tier or public per-GB pricing is available, as plans are tailored for high-security use cases. Volume-based discounts are offered for committed contracts. Pricing details are available at https://www.imperva.com/pricing/. The model suits large organizations but may be cost-prohibitive for smaller businesses.
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.
Imperva provides APIs for configuration and management, supporting an API-first approach. Realtime logs and analytics are accessible via the Imperva Management Portal, with log push for integration into external systems. No public documentation confirms Terraform or specific SDK support, limiting Infrastructure-as-Code (IaC) options. Migration tools are not emphasized, but the platform supports standard CDN configurations. Developers may find the API robust but less flexible for CI/CD pipelines compared to Fastly or Akamai.
When it fits
- Businesses targeting APAC and China markets, especially those needing MIIT-compliant CDN services.
