iCloud – The cloud storage version of Apple helps you connect all your Apple devices, and therefore provides a seamless experience across all your Apple devices. Just for an example if you leave writing an email on your iPhone you can pick it up on your iPad or Mac exactly from where you left. You can also share photos, locations etc. with your family and peers. Following are the features that you can see in iCloud.
iCloud Drive - As soon as you sign up for iCloud using your Apple id you get a 5GB storage for Free. So, if you are working on a document in any of your device you could actually sync and upload it on the iCloud Drive of yours, and can easily access this document from any other Apple device. Post 5GB of free storage you can easily buy more storage at a nominal cost.
Family Sharing - iCloud also provides you flexibility of sharing your stuff with your family. So, you can share iTunes, iBooks, Photos, location etc. with up to six members of your family.
Photos and iTunes - Family sharing allows photos, videos and you get full rights to share only what you want to share and to whom you want it to see. The people with whom your photo stream is shared can comment on them. With iTunes the possibility of carrying your entire collection is so very possible. Again this all is accessible from all your Apple devices.
Find My iPhone and other devices - This feature is of great help in situation when you had lost your iPhone, iPad or anyother Apple device.
