Which cloud model provides retention of governance controls to a large company with legacy systems?

The Private cloud model provides the greatest retention of governance controls for large organizations with legacy systems. Managing Cloud guidance explains that private clouds are dedicated environments operated solely for one organization, either on-premises or hosted by a third party.

This model allows companies to maintain strict control over security policies, compliance requirements, data governance, and system configurations. Legacy systems that require specific architectures, custom integrations, or regulatory oversight can be more easily accommodated in a private cloud environment.

Public clouds offer limited control, community clouds share governance across organizations, and hybrid clouds introduce additional complexity. Therefore, private cloud is the most appropriate model for retaining governance controls with legacy systems.
