Define a private cloud and explain how it is used.
What will be an ideal response?
If a business wants some of the flexibility of the cloud, needs complete ownership of its data, and can afford both, it can build an internal cloud the business actually owns-a private cloud. A security-minded company with enough resources could build an internal IaaS network in an onsite data center. Departments within the company could create and destroy virtual machines as needed, and develop SaaS to meet collaboration, planning, or task and time management needs all without sending the data over the open Internet. A company with these needs but without the space or knowledge to build and maintain a private cloud can also contract a third party to maintain or host it.
