NIST definition of Private Cloud: Private cloud is a cloud computing model operated solely for a single organization. It can be managed internally or by a third party. It can be hosted behind the company firewall or externally.
A private cloud (also known as an internal cloud or a corporate cloud) is a type of cloud architecture that is dedicated to a single business or organisation.
As per Microsoft Azure: The private cloud is defined as computing services offered either over the Internet or a private internal network and only to select users instead of the public.
In the case of a public cloud, a service provider offers his resources (like storage capacity and computing power) to a client. The private cloud, on the other hand, allows organizations to use their own infrastructure or a Cloud service provider can offer dedicated hardware, network, and infrastructure to the client. The infrastructure can be hosted either within the organization itself or externally.
