iCloud is a cloud storage and cloud computing service from Apple Inc. launched on October 12, 2011. As of July 2013, the service had 320 million users. Apple release a stable version 4.1 / April 30, 2015, 5 days ago. iCloud is designed to work seamlessly with all your Apple devices connected to the Internet. For example, you can upload photos from your iPhone and access them from your MacBook, upload music from your MacBook to listen to from your iPod Touch, or upload an important document from your Mac desktop to access from your iPad when you’re on the go.The service provides its users with means to store data such as documents, photos, and music on remote servers for download to iOS, Macintosh or Windows devices, to share and send data to other users, and to manage their Apple devices if lost or stolen.
The service also provides the means to wirelessly back up iOS devices directly to iCloud, instead of being dependent on manual backups to a host Mac or Windows computer using iTunes. Service users are also able to share photos, music, and games instantly by linking accounts via AirDrop wireless.
iCloud replaced Apple’s MobileMe service, acting as a data syncing center for email, contacts, calendars, bookmarks, notes, reminders (to-do lists), iWork documents, photos and other data.
One of Apple’s iCloud data centers is located in Maiden, North Carolina, US.
Features:- The cloud-based system allows users to store music, photos, applications, documents, bookmarks, reminders, backups, notes, iBooks, and contacts, and provides a platform for Apple’s email servers and calendars. Third-party iOS and OS X app developers are able to implement iCloud functionality in their apps through the iCloud API.
Backup And Restore:- iCloud allows users to back up the settings and data on iOS devices running iOS 5 or later.Data backed up includes photos and videos in the Camera Roll, device settings, app data, messages (iMessage, SMS, and MMS), ringtones, and Visual Voicemails. Backups occur daily when the device is locked and connected to Wi-Fi and a power source.
Back to My Mac:- Back to My Mac, also previously part of MobileMe, is now part of iCloud.As before, this service allows users to log in remotely to other computers that have Back to My Mac enabled and are configured with the same Apple ID.
Find My Friends:- Find My Friends was a new feature introduced to iCloud in iOS 5. Find My Friends is very similar to Find My iPhone, except users can share their location with other friends or family using the feature. Concurrently with the launch of iOS 5, Apple released an app for Find My Friends. iOS 6 added location-based alerts to notify the user when a device arrives at a certain location.
iCloud Keychain:- iCloud Drive is iCloud’s file hosting servicefor devices running iOS 8, OS X Yosemite(version 10.10), or Windows 7or later, plus online web appaccess via iCloud.com.
