Managed Private Cloud refers to a principle in software architecture where a single instance of the software runs on a server, serving a single client organization (tenant), and managed by a third-party. This is in contrast to multitenancy where multiple client organizations are on a single server, or an on-premises deployment where the client organization hosts their own instance.
Managed Private Clouds also fall under the larger umbrella of cloud computing.
