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.
This chart shows key benefits [1] of the different types of deployments, and shows the overlap.

Since deployments are done in a single-tenant environment, it is usually cost-prohibitive for small and medium-sized businesses.
Common Customizations [2] and Integration include:
- Active Directory
- Single Sign-on
- Learning Management Systems
- Video Teleconferencing
Different Deployment Strategies
Software companies have taken a variety of strategies in the Managed Private Cloud realm. Few software companies have provided managed private cloud options internally. Companies that offer an on-premises deployment option, by definition enable third-party companies to market Managed Private Cloud solutions.
Adobe
Adobe Connect may be purchased for on-premises deployment, multi-tenant hosted deployment, managed private cloud as ACMS,[3] or managed by third-party managed private cloud provider ConnectSolutions.[4]
Microsoft
Microsoft licenses for Lync, Sharepoint and Exchange may be purchased for on-premises deployment, a multi-tenant hosted deployment via Office 365,[5] or managed by third-party cloud hosting for from Azaleos,[6] ConnectSolutions[7] and others.
Others
Popular webconferencing products like Cisco WebEx, Citrix Go-to-Meeting and Skype are available via multitenancy, and not available in a managed private cloud environment.
