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.
KeyCDN is CDN provider from Switzerland with 24 points-of-presence (PoPs) worldwide, and 8 more PoPs planned. The CDN service is part of proinity GmbH, a Swiss IT services company that’s also behind image optimiser Optimus.
KeyCDN was founded in 2012 by Jonas Krummenacher and Sven Baumgartner. Their network is non-federated; the entire infrastructure is owned by KeyCDN.
The provider’s feature offering includes two-factor authentication, DDOS protection, origin shield, real-time reporting and more than 24 CMS integrations such as with WordPress, Magento and Joomla.
