What distinguishes a community cloud?

A community cloud is characterized by its shared ownership and support among several organizations that have similar interests or requirements. This model allows those organizations to leverage a single, pooled infrastructure while benefiting from collaboration and shared resources, typically designed to meet specific regulatory, security, or performance needs relevant to the group's purpose.

In contrast to other cloud deployment models, a community cloud enables organizations to address specific challenges collectively, enhancing efficiency and cost-effectiveness. It fosters collaboration in a way that is not achievable in public clouds, where resources are available to the general public, or in private clouds, which are isolated to a single organization. The focus on shared interests sets community clouds apart and is what makes option C the correct choice.
