Which of the following is a cloud infrastructure that is shared by several organizations and supports a specific group that has shared concerns?

Public Cloud infrastructure is provisioned for open use by the general public, not restricted to a specific group of organizations with shared concerns.

Private Cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers, not shared across multiple organizations.

Community Cloud is specifically defined as infrastructure provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns - such as mission, security requirements, policy, or compliance considerations. It may be owned and managed by one or more organizations in the community, a third party, or a combination, and may exist on or off premises.

Hybrid Cloud is a composition of two or more distinct cloud deployment models (public, private, or community) bound together, not a standalone model for shared organizational use.

Common Cloud is not a recognized cloud deployment model in NIST or any standard cloud computing taxonomy.
