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.
Not to be confused with Amazon Cloudfront, CloudFlare is a San Francisco-based CDN provider founded in 2009.
The company offers a Free plan, which includes a CloudFlare issued SSL certificate. The features included in the Free plan are basic; more become available to Pro, Business and Enterprise customers.
CloudFlare, together with Akamai, Fastly, Highwinds, Level3 and EdgeCast, is part of the Google Cloud Platform CDN Interconnect program. As part of the collaboration, 30 CloudFlare points-of-presence (PoPs) are directly connected to the Google Cloud infrastructure. When a content request comes in from a Google Cloud origin it will route directly through the interconnect between both parties rather than through the public Internet. As a result, latency is reduced for origin requests. Clients using Google Cloud also receive a discount to their egress traffic.
