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.
Level3 Communications is an Internet Service Provider (ISP) and a provider of telecommunication services. The company was founded in 1885 and is currently headquartered in Colorado, in the United States. The Level3 brand is well-known; the company operates a large, physical network of the Internet and offers a wide range of networking services. Level3 is the network, and it owns a Tier 1 backbone and operates its own points-of-presence (PoPs). One notable customer of Level3 is Netflix.
Level3 has made some notable acquisitions, including companies such as Black Lotus (DDoS protection), TW Telecom (business Internet solutions), Genuity (AS1) and the CDN services business of Savvis - a subsidiary of CenturyLink that provides hosting and colocation services. The CDN was acquired in 2006 and is run by Level3 to this day. In 2016 Level3 has been acquired by CenturyLink.
Additional CDN-related services by Level3 include DDoS protection, SSL, Encryption, Geo Blocking, (live) video streaming and website acceleration.
Together with Fastly, CloudFlare, Highwinds, Akamai and EdgeCast, Level3 is part of the Google Cloud Platform CDN Interconnect program. The interconnection agreement between the backbones of both parties will benefit customers on both sides; traffic over these interconnects enjoys reduced latency and increased reliability compared to the public Internet. Clients using a Google Cloud origin receive a discount to their egress traffic when peering with Level3 or any other CDN that is part of the collaboration.
Level3 does not publish customer information. CDN overview has located some of customers of the CDN service, such as CloudVPS. We’ll keep the list updated.
