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.
Cloudfront is a CDN by Amazon, which can be used on a stand-alone basis, or in combination with other Amazon web products.
The CDN integrates very well with Amazon Web Services (AWS), and is often used in combination with their storage solution Amazon S3.
Amazon Cloudfront offers on-demand, no-commitment pricing plans which can be found on their website. The pricing overview of Cloudfront is slightly complex; customers should be aware that the unit prices for bandwidth and requests differ per region.
