Private cloud computing is an IT strategy in which scalable computing power and software resources are made available to the user via the Internet
. Private cloud computing differs from public cloud computing in that private cloud computing can only be used by one organization, company or individual; whereas in public cloud computing, access is open to all. Therefore, private cloud computing is mainly used by those organizations that want to have control over the cloud services
that only their own employees can access. Private cloud computing does not necessarily have anything to do with private cloud, where the computing power of one's own data center is brought into the cloud. Private cloud computing can be provided by external third-party providers who provide the cloud services, but the user manages their implementation. Whether the services are provided by an external provider or an in-house provider depends on the nature of the organization and its attitude towards third-party providers.
