Techopedia Explains iCloud
iCloud is a hybrid cloud solution that combines infrastructure and software services to provide a suite of apps and services, enabling users to add, remove and synchronize typical data files, contacts and bookmarks on selected Apple devices. This data is then stored and backed up on iCloud’s remote storage server.
iCloud automatically uploads a photo taken from a Photo Stream-enabled device to cloud storage, while media files purchased from iTunes are also made available to all shared devices through iCloud. iCloud also features Find my Phone, which enables users to track, access and edit the content on their iPhone, iPod Touch, iPad or Mac remotely.
