Definition

A private cloud is a cloud infrastructure

provisioned for exclusive use by a single organization comprising multiple cloud service customers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises.[1]

Overview

A private cloud gives a single cloud consumer's organization the exclusive access to and usage of the infrastructure and computational resources. It may be managed either by the cloud consumer organization or by a third party, and may be hosted on the organization's premises (i.e., on-site private clouds) or outsourced to a hosting company (i.e., outsourced private clouds).

In private clouds, services are provided exclusively to trusted users via a single-tenant operating environment. Essentially, an organisation's data centre delivers cloud computing services to clients who may or may not be in the premises.[2]
