Managed private cloud

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.

Benefits and Challenges of Managed Private Cloud

Customers who choose a managed private cloud deployment usually choose them because of their desire for an efficient cloud deployment, but the need for customization or integration only available in a single-tenant environment.

Companies that offer an on-premises deployment option, by definition enable third-party companies to market Managed Private Cloud solutions.
