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.
ChinaNetCenter is one of the leading Chinese Internet service platform providers that offers both coverage of mainland China and in the rest of the world. ChinaNetCenter was founded in 2000 and was listed on the Shenzhen Stock Exchange in 2009. Its US subsidiary MileWEB was set up in 2012 and tasked with globalising ChinaNetCenter’s CDN services. Global sales operations followed in 2014 and MileWEB was renamed to Quantil.
The company has over 500 ‘CDN nodes’ in mainland China, covering all the major cities. Another 60 of these CDN nodes, what we assume are PoPs, are located in Europe and the United States. Next to CDN services, ChinaNetCenter offers server hosting and rental.
Features or products offered by ChinaNetCenter include the usual, such as download delivery, site acceleration, mobile acceleration and media streaming.
Note that international businesses require an Internet Content Provider (ICP) license to operate their site from China. Most Chinese CDN providers such as ChinaNetCenter and Quantil offer support to clients applying for the ICP license. Mind that without a license, Chinese ISPs are required to restrict access to the website.
