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.
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.
