ICloud provides a cloud storage service that is able to connect a wide variety of Apple products and allow Apple users to access important files from every device. As of 2015, Apple users enjoy 5 gigabytes storage on iCloud for free but can pay a monthly subscription for more space.
It is simple to set up iCloud on various Apple devices, including an iPhone, iPod touch, Mac and iPad, through a built-in setup assistant. Older Apple devices generally do not have a setup assistant but can still connect to the iCloud.
Some of iCloud features that users can access on Apple devices include the iCloud Photo Library, iCloud Drive, Family Sharing and iTunes Everywhere. The iCloud Photo Library allows Apple users to access photos and videos uploaded to iCloud from any connected Apple device. Users can also allow family and friends to upload and comment to the same iCloud account. ICloud Drive allows Apple users to upload and store various types of files, including PDFs, spreadsheets and presentations.
ICloud's Family Sharing feature makes it possible for up to six additional people to access and share data with each other's iCloud storage. This includes files purchased from the App Store, iBooks and iTunes.
