Which cloud infrastructure is shared by several organizations and supports a specific population with shared concerns?

The correct choice is the community cloud, which is specifically designed for several organizations that share common interests, needs, or concerns. This type of cloud infrastructure allows those organizations to collaborate and share resources while ensuring that their specific requirements are met. It typically offers a more tailored approach compared to public clouds, providing services that are suited to the unique regulatory, security, or compliance needs of the shared user group.

Community clouds foster collaboration and resource-sharing among organizations with similar missions, making them ideal for sectors such as education, healthcare, or government, where entities might require similar infrastructure for their operations. This infrastructure allows for cost efficiencies by pooling resources and enables enhanced communication and data sharing among the organizations involved.
