Which cloud infrastructure is shared by several organizations with common concerns, such as mission, policy, or compliance considerations?

The community cloud is designed specifically for a group of organizations that share common interests, such as mission objectives, policy concerns, or compliance requirements. This type of cloud infrastructure allows these organizations to collaborate while ensuring that their specific needs are met. By pooling resources, organizations in a community cloud can benefit from shared services while adhering to the necessary compliance and policy standards that govern their operations.

In contrast, a private cloud is dedicated to a single organization, providing greater control and customization but lacking the shared benefits of collaboration with others. A public cloud is available to the general public and is not limited to organizations with common interests, making it less suited for those with specific compliance or policy needs. Finally, a hybrid cloud combines public and private cloud elements but does not inherently focus on the shared concerns of multiple organizations as in the case of a community cloud. Thus, the community cloud is the most appropriate choice for entities with common goals and compliance needs working together in a shared infrastructure.
