Private Cloud
In plain terms
Cloud infrastructure dedicated to a single organization.
Going deeper
A private cloud provides cloud-like services on infrastructure exclusively for one organization, on-prem or hosted. It offers more control and isolation.
Under the hood
Greater control and compliance at higher cost and less elasticity than public cloud.
Examples
Banks, government, regulated industries, OpenStack, VMware private clouds.
Think of it like...
Like owning your own data center but running it with cloud conveniences.
