Alibaba Cloud is a part of the Alibaba Group which specializes in cloud computing. The products under Alibaba Cloud include a CDN solution, an SSL service, Cloud storage, and Elastic Computing amongst others. Since the CDN solution is part of the Alibaba Cloud family of products, it is naturally integrated with most of the other products.
Alibaba’s CDN solution is primarily focussed on China, with most of its nodes located on the Chinese mainland. They do also have some PoPs overseas. However, since these aren’t included in standard use, they are excluded from our pop count.
CDNetworks has been around since 2000, and is currently headquartered in Seoul. The company has raised capital with Shinhan Private Equity, Goldman Sachs and Oak Investment Partners, and acquired CDN competitor Panther Express in 2009. The company was bought by Japanese Telco KDDI in 2011. The provider has 169 points of presence (PoPs) worldwide.
CDNetworks offers the usual services within the CDN ecosystem, such as DDoS protection, cloud storage, Web Application Firewall (WAF), managed DNS with load balancing and video acceleration.
The CDN provider has a strong presence in emerging Internet markets such as China, Russia, India and South America. The company operates in mainland China and has been doing so for over 10 years. Currently, CDNetworks has 21 PoPs within China, which are mostly concentrated in the east of the country. The company is licensed by the Chinese government, and their CDNetworks China Acceleration service can be an alternative to homegrown CDN providers ChinaNetCenter and ChinaCache.
Similar to China acceleration, CDNetworks has a special focus on Russia. With 16 PoPs across the country, and a partnership with network operator MegaFon, CDNetworks offers a broad range of delivery services in Russia.
