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.
CacheFly is a Chicago-based CDN provider, with over 40 Points of Presence (PoPs) spread over six continents. Next to the usual locations, Cachefly has PoPs in India, Qatar, Egypt and South Africa.
The Cachefly network is optimised for throughput, making it more suitable for the delivery of large files.
Instead of DNS-based global loadbalancing, the company’s CDN infrastructure relies on TCP Anycast routing.
CacheFly offers the usual features in the CDN industry such as instant purge, origin shielding, real-time reporting and sub-accounts. They also offer a 100% availability SLA and 24⁄7 support.
