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.
Tata Communications, a company of Indian multinational Tata Group, offers a CDN service with 400 points-of-presence (PoPs) on five continents, in 21 locations. Tata owns and operates an impressive network infrastructure, with their sub-terrestrial and sub-sea network spanning 700,000 kilometers - more than 17 times around the world. According to the company, 24% of the planet’s internet routes are on their network, which grants improved performance and flexibility.
In 2011, Tata Communications acquired BitGravity - a US-based CDN provider founded in 2006. BitGravity. The companies had been in a strategic alliance leading up to the acquisition, and the move was a logical next step for Tata Communications to improve its global CDN offering. Remnants of BitGravity can still be found, such as the Tata Communications CDN support portal.
Tata Communications offers a wide range of CDN features such as live streaming and video-on-demand (VOD), an out-of-the-box online video platform, site acceleration and software delivery. They also provide DDoS and security services, hosting, colocation and transit.
