Which cloud infrastructure is shared by several organizations with specific shared concerns?

The correct choice reflects the concept of a community cloud infrastructure, which is specifically designed to be shared among multiple organizations that have common interests, goals, or specific regulatory and compliance requirements. In a community cloud, the infrastructure is tailored to meet the shared needs of organizations, providing a collaborative environment where they can share resources, such as computing power and storage, while also addressing concerns such as security, performance, and management.

Organizations using a community cloud typically have similar cloud-related requirements, enabling them to benefit from reduced costs as they share the underlying infrastructure. This contrasts with the other types of cloud infrastructure. A public cloud is available to anyone and is not restricted to a particular group, while a private cloud is exclusive to one organization, providing tailored resources without sharing. A hybrid cloud combines elements of both public and private clouds, allowing data and applications to be shared between them, but it does not specifically cater to a set of organizations with shared interests as the community cloud does.
