Which term describes a shared infrastructure among several organizations with common concerns?

The term that describes a shared infrastructure among several organizations with common concerns is the Community Cloud. This type of cloud computing environment allows multiple organizations, often within the same industry or with similar interests, to collaborate and share resources while benefiting from a common infrastructure.

Community clouds are specifically designed to address the collective needs of these organizations, enabling them to maintain a greater level of control over their data while also benefiting from cost savings associated with shared resources. This collaboration can help improve security and compliance for members of the community, as they usually have similar requirements regarding data protection and regulatory guidelines.

In contrast, a Public Cloud refers to services offered to the general public over the Internet and is not restricted to any particular organization. A Private Cloud is dedicated to a single organization, providing enhanced privacy and control but does not offer the collaboration aspect found in a Community Cloud. A Multi-tenant Cloud typically refers to architecture that supports multiple users or tenants within a single infrastructure but does not necessarily imply a shared infrastructure among organizations with common concerns, focusing more on resource efficiency rather than collaborative needs.
