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.
HolaCDN is the video CDN from Hola, an Israel-based company known for their Hola VPN and peer-to-peer (P2P) technology, and P2P data mining service Luminati.io.
The solution lets customers combine their own CDN with the network of HolaCDN, to optimise video delivery. The delivery process takes place in two phases:
Customers can integrate the CDN with a variety of existing, third-party video players or use the Open Source Hola Player.
HolaCDN does not publish their network map or the amount and locations of their of points of presence (PoPs). Their network does not need to be extensive due to the nature of video loading: only the initial chunk needs to be served out quickly, what follows is less relevant. So, as far as their network goes – we can only guess.
