Apple has been building a fleet of large datacentres over the past few years without saying why. It is known to operate facilities in Newark, California, along with Maiden, North Carolina. In May it signed a seven-year lease with DuPont Fabros Technology for additional co-location space in Santa Clara, California.

iCloud is thought to contain a music service that, unlike rival products from Amazon and Google, has the backing of three of the four major music labels.
