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.
Microsoft’s cloud computing platform Microsoft Azure includes a CDN service in their offering. The platform was released in 2010, initially named Windows Azure and renamed to Microsoft Azure in 2014.
Azure is an Infrastructure-as-a-Service (IaaS) solution, and next to a CDN they offer storage solutions, data management, compute and networking. Their IaaS solution is similar to Amazon Web Services (AWS) and Google Compute Engine (GCE). Just like Google, Azure offers free credit to first-time users of the platform to help them get started.
The Azure CDN service uses the networks of Akamai and Edgecast, though it is fully integrated with the cloud platform and offered under the Azure brand. Because the CDN service is offered as a part of the larger Azure IaaS ecosystem, it is easy-to-use for businesses who already use the platform. Other CDNs can be used in combination with Azure products as well, for example with their storage solution.
