Apple : Reportedly Apple is negotiating paid interconnect deals with ISPs for their own CDN - tech blogs
Apple is currently negotiating paid interconnection deals with some of the largest ISPs in the U.S. Im not going to disclose which ISPs they are talking to and what deals they have already done, but its interesting to note that with all the talk lately of net neutrality, peering and interconnect relationships, Apple isnt out in the market making any complaints. While Netflix has used the media, consumers and lawmakers to try and argue that CDNs should get as much peering as they want, at no charge, Apple doesnt seem to agree with that sentiment. If they do, they certainly arent complaining in any public forum.
Part of Apples reasoning for building their own CDN is because of performance issues with iCloud, with Apple wanting to have more control over the end-user experience. Apple already controls the hardware, the OS and the iTunes/App store platforms. Right now Apple controls the entire customer experience, except for the way content is delivered to their devices, so its only natural that a company of their size would build out their own CDN.
