iCloud refers to all the services that Apple provides to its users through internet. iCloud helps to keep all of your Apple devices synchronized. The different apps are shared between different Apple devices. When your iPhone and Mac are connected to the iCloud then the pictures taken from your iPhone can also be seen on Mac. iCloud synchronizes everything like iTunes, contacts, messages, media, calendar, notes and reminders as well as your safari bookmarks.


iCloud Drive

You can have 5GB free space in your iCloud provided by Apple. The space over the internet used to store your documents and pictures are called iCloud drive and can be accessed by multiple devices. You cn also upgrade the iCloud storage space by buying more iCloud Storage space.

iCloud Photo Library

Whenever you take photos My Photo Stream uploads it to the cloud and you can see them in other devices signed up for My Photo Stream service. However it is not a good deal when you find that the photos disappears from the cloud. Therefore Apple introduces iCloud Photo Library which is the new version of My Photo Stream. It holds every photo and you can have them anytime you want without the fear of losing any of them. However the iCloud photo Library is not the part of iCloud drive but it is still a useful service provided by Apple to keep your Photos in the iCloud.
