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.
Azion Technologies is a CDN provider with strong presence in Latin America. While their global coverage is limited, the provider has a large amount of points-of-presence (PoPs) in LATAM and particularly in Brazil. The company currently has 25 PoPs in its network and plans to add an additional 26 in the future.
Features offered by Azion include, but are not limited to: media acceleration, security, live streaming and image optimisation.
Azion was founded in 2011 and has three offices in Porto Alegre, São Paulo and in Miami.
