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.
NS1, now IBM NS1 Connect, specializes in DNS traffic steering and MultiCDN solutions to optimize application delivery. Founded in 2013 and acquired by IBM in 2023, it serves enterprises needing precise control over traffic routing across multiple CDNs and cloud providers. Its flagship product, NS1 Connect, uses real-time data and automation to enhance performance and resilience. Customers include large-scale organizations in tech, finance, and media sectors. The platform integrates with various CDNs and cloud services to manage global traffic efficiently.
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.
NS1 operates a global network with 26 points of presence (PoPs) across North America, EMEA, APAC, and other regions, ensuring low-latency DNS resolution. Its architecture leverages authoritative DNS and real-time data for traffic steering, with robust peering to major cloud providers and CDNs. The platform supports hybrid deployments, combining on-premise and cloud DNS for flexibility. It excels in global coverage but may have less focus on niche regional markets like Africa or the Middle East compared to telecom CDNs.

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.
NS1 operates on an enterprise-only model with custom pricing based on traffic volume and feature sets. No public per-GB pricing is available, and there’s no free tier or pay-as-you-go option. Contact IBM for pricing details.
