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.
Texas-based cloud computing company Rackspace was founded in 1998 and is quite the household name. With their ‘Fanatical Support’ concept, the company distinguishes itself from its competitors by offering to focus on service and support rather than technology.
The core businesses of Rackspace are dedicated servers and cloud servers, though the company has a large portfolio with web services. Among others, the company offers website hosting, application migration, Software-as-a-Service (SaaS) and Apps hosting, database and data analytics, email hosting and CDN services.
The company’s CDN is powered by Akamai, and Rackspace resells a custom map with 200 points-of-presence (PoPs):
Note that a limitation to the Rackspace CDN is that clients can only add up to 10 domains (resources) per service.
Rackspace offers a free web-based application called Rackspace Marketplace that enables clients to manage a variety of business applications in a single place. Some of the partnered apps in the Marketplace can also be purchased directly via Rackspace. Currently, the Rackspace Marketplace has integrations with:
Other * New Relic * Cedexis * Neustar UltraDNS * Dynatrace * W3 Total Cache
