Private cloud
A private cloud serves one organisation and can be operated externally. Exclusive use does not replace a clear agreement on operational responsibilities.
What does private cloud mean?
A private cloud provides cloud resources exclusively to one organisation, such as several departments of the same company. NIST allows operation by the organisation or third parties, at internal or external locations. Private cloud therefore does not necessarily mean that all equipment is in your own building.
A single reserved server is not enough to make it a cloud. Cloud characteristics also matter, such as on-demand provisioning and a managed resource pool. Microsoft likewise describes a private cloud as an environment for one organisation. That boundary does not establish that each application’s security has been verified.
Externally operated, shared internally
In the fictional example, a service provider operates environment ENV-42 exclusively for one company. Its development and service teams can request test environments themselves under defined rules. The teams share resources within the organisation; the provider’s other customers do not use this private cloud.
Who may allocate capacity, change access and update systems? Who tests backups and restores the application? Record these tasks in the operating model. The private cloud label does not assign them. If you only need to host a single application, compare the additional platform operations with a simpler offering suited to that task.
