Usually, a cloud can be either privatise of publicly owned. A publicly owned cloud sells its services to anyone and everyone in the visual world; and presently, the largest cloud hosting provider is Amazon. A privatised cloud is when a cloud hosting provider sells their services to a selected number of people. Also there are times when a cloud hosting provider utilises a public cloud resources to form their private cloud, and such event suggests virtual private cloud. However, privatised or publicly owned, the function of cloud computing is to offer an easy yet straight forward entry to computing resources or IT services.
