Behind Every iCloud
With iOS 5, Apple introduced iCloud, the latest in its line of Internet-based tools and services. To the end user, iCloud extends Apple’s previous MobileMe offerings of e-mail, contact management, and Find My iPhone, with iOS backup and restore, iTunes Match, Photo Stream, and Back to My Mac. With iOS 8, iCloud got a major overhaul and has included a new framework called CloudKit. This provides you with authentication, private and public database structures, and asset storage services.
