In 2014, Comcast debuted their CDN service. With their own CDN in place, Comcast can deliver a better experience to their already existing consumer base. Unique in the CDN landscape, we can label Comcast a B2C CDN service provider.
As the ISP, cable owner and CDN provider, Comcast is able to offer an excellent SLA and potentially lower pricing, when compared to 3rd party CDN providers who do not own the network they operate on.
The Comcast CDN is regional and offers PoPs within the US only. The CDN service is therefore not suited for businesses with a global userbase, unless it is combined with other CDN providers in a multi-CDN setup. Warpcache is a multi-CDN provider that offers the Comcast CDN in combination with others.
Comcast is a very suitable provider for a multi-CDN setup. Warpcache resells multiple providers, both in an integrated multi-CDN solution and separately.
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.
