Which cloud model is limited to a specific group of individuals and addresses policy and audit access concerns?

The community cloud model is designed specifically for a group of organizations or individuals who share common concerns, whether those are related to policy, security, or compliance requirements. This model facilitates collaboration within the defined group while ensuring that access and governance policies align with their specific needs.

One of the primary advantages of a community cloud is its ability to address audit and access control issues, a critical area for organizations operating under stringent regulations or that require a higher level of data protection. By limiting access to a specific community and ensuring that all members adhere to the same policy standards, the community cloud fosters a secure shared environment.

The public cloud provides resources and services to the general public, lacking the targeted governance this scenario requires. The private cloud is dedicated to a single organization, which can lead to an isolated environment but doesn't inherently involve collaboration with other organizations. The hybrid cloud combines elements of both private and public clouds, allowing data and applications to be shared among them while still lacking the focused policy framework characteristic of a community cloud.

Thus, the community cloud model uniquely fits the context of collaborative groups requiring shared control over audits and access policies.
