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 several organizations that share common concerns, such as mission, policy, or compliance needs. This infrastructure allows organizations within a particular sector or with specific regulatory requirements to collaborate and utilize shared resources while maintaining a level of security and privacy that might not be possible in a public cloud environment.

By using a community cloud, participating organizations can benefit from the cloud's scalability and cost-effectiveness while ensuring that their unique needs and compliance obligations are adequately addressed. This model fosters collaboration and resource sharing among organizations with similar objectives, thereby promoting efficiency and compliance without compromising security.

In contrast, other cloud deployment models such as private, public, and hybrid clouds do not focus primarily on the shared concerns of multiple organizations to the same extent as community clouds do. Private clouds are dedicated solely to one organization, public clouds are available for general use by anyone, and hybrid clouds combine elements of both private and public clouds but do not necessarily cater to a specific community of organizations with common compliance needs.
