"There are four main types of cloud storage: Personal Cloud
Storage - Also known as mobile cloud storage, personal cloud
storage is a subset of public cloud storage that applies to storing
an individual's data in the cloud and providing the individual with
access to the data from anywhere. It also provides data syncing and
sharing capabilities across multiple devices. Apple's iCloud is an
example of personal cloud storage.
"Public Cloud Storage - Cloud storage where the enterprise and
storage service provider are separate and there aren't any cloud
resources stored in the enterprise's data center. The cloud storage
provider fully manages the enterprise's public cloud storage."
