Which cloud model provides an exclusive cloud computing service environment that is shared between two or more organizations?

The community cloud model is designed to provide an exclusive cloud computing environment that is shared among two or more organizations with common goals, interests, or regulatory requirements. This shared environment allows organizations to collaborate while maintaining control over their data and applications.

Organizations may use a community cloud to share resources and infrastructure, which may lower costs and improve efficiency by leveraging the cloud for specific community needs, such as compliance, security, or even collaborative projects. Each participating organization benefits from the mutual interests and shared regulations, making this model particularly suitable for sectors such as healthcare, education, or government where the requirements and needs may overlap significantly.

In contrast, the public cloud model is accessible to anyone and serves a broad range of users without exclusivity. The private cloud is dedicated to a single organization, providing more control and security but lacking the shared benefit. The hybrid cloud combines elements of both public and private clouds, allowing for flexibility but does not focus on the shared environment between multiple organizations like the community model does.
