Founded in 1998, ChinaCache is one of the earliest CDN providers in China. The company has a large coverage of mainland China, with additional points-of-presence (PoPs) in the rest of the world. The CDN services of ChinaCache are exploited through different divisions, such as NovaCDN and Webluker.
ChinaCache has a 120 points of presence (PoPs) in mainland China, in all major cities and regions of the country. They service well-known brands such as Big Fish Games, Uber, LinkedIn, Coach, Intel and Adobe.
Businesses operating their website in China require an Internet Content Provider (ICP) license. While not mandatory, Chinese Internet Service Providers are required to restrict access to sites without such a license. ChinaCache provides business with support to obtain an ICP license.
ChinaCache has offices in Hong Kong, Beijing, London and the US.
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.
