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.
Vercara, formerly Neustar Security Services, is a cloud-based provider of CDN, DNS, and cybersecurity solutions, focusing on enterprise-grade services. It offers UltraDNS for managed authoritative DNS and UltraDDoS Protect, UltraWAF, UltraAPI, and UltraEdge for security and performance. Acquired by DigiCert in September 2024, Vercara serves over 2,000 enterprises, including Fortune 500 companies, across industries like finance, e-commerce, and healthcare. Its solutions emphasize uptime, security, and scalability for complex digital infrastructures. Vercara handles approximately 30% of global internet traffic, processing over 9 trillion DNS queries daily.

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.
Vercara operates a global network with points of presence (POPs) across 16 regions, including a recently added node in Toronto. Its UltraDNS service ensures low-latency DNS resolution, and its DDoS mitigation network has a capacity exceeding 15 Tbps. The platform is designed for high availability, with a reported 100% uptime for DNS services. It has strong regional coverage in North America, EMEA, and APAC, serving global enterprises with hybrid cloud setups. Specific peering and routing details are not publicly disclosed, but Vercara’s infrastructure supports major hyperscalers and high-traffic verticals.

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.
Vercara operates on an enterprise-only model, with pricing tailored to customer needs and no public per-GB rates disclosed. It does not offer a free tier or pay-as-you-go options, focusing on committed contracts for large organizations. Specific pricing details are available only through direct sales consultation. No public pricing page is provided.

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.
