Shared Cloud Infrastructure

D.

The correct answer is D. Community.

A community cloud infrastructure is a type of cloud computing model where several organizations with similar structures and interests share the same cloud infrastructure. This infrastructure is designed to meet the specific needs of a community, such as healthcare or finance, where the data sharing and collaboration are essential.

The community cloud model provides a level of control and privacy that is not available in public clouds while also offering cost savings through shared resources. It provides a shared pool of computing resources, including servers, storage, and applications, that can be accessed by multiple organizations within the community.

In a community cloud, the infrastructure is managed and maintained by a third-party provider, and each organization has its own virtualized infrastructure and a layer of security and control over their data. The provider ensures the security, availability, and maintenance of the infrastructure, while each organization has control over their data and applications.

Private cloud infrastructure is a cloud computing model where the infrastructure is dedicated to a single organization, and the organization has complete control over its infrastructure. Hybrid cloud infrastructure is a combination of two or more cloud computing models, where the infrastructure is a mix of public, private, and community cloud infrastructures. Public cloud infrastructure is a cloud computing model where the infrastructure is available to the general public or a large industry group and is owned by a third-party provider.

In summary, a community cloud infrastructure allows several organizations with similar structures and interests to share resources, provides a level of control and privacy, and is managed by a third-party provider.
