Shared Cloud Deployment

B.

In Community cloud, the cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations)

It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises.

For your exam you should know below information about Cloud Computing deployment models: Private cloud - The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units)

It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises.

Public Cloud - The cloud infrastructure is provisioned for open use by the general public.

It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them.

It exists on the premises of the cloud provider.

Public Cloud -

Hybrid cloud - The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds) hybrid cloud.

The following answers are incorrect: Private cloud - The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units)

The cloud deployment models are Private Cloud, Public Cloud, Community Cloud, and Hybrid Cloud.

A Private Cloud is a cloud computing model where resources are dedicated to a single organization, and it is used exclusively by that organization. It is not shared with other organizations or individuals. The organization owns and manages the infrastructure, applications, and data on the private cloud.

A Community Cloud is a cloud computing model where resources are shared by several organizations with a common goal or purpose. It is designed to provide a shared infrastructure and platform for a specific community or group of organizations. Members of the community can share applications, services, and data on the community cloud.

A Public Cloud is a cloud computing model where resources are provided by a third-party service provider and are available to the general public over the internet. It is a shared infrastructure that is accessible to anyone who has an internet connection. The service provider owns and manages the infrastructure, applications, and data on the public cloud.

A Hybrid Cloud is a cloud computing model that combines two or more cloud deployment models (private, public, or community) to meet the organization's specific requirements. It enables organizations to leverage the benefits of both private and public clouds, allowing them to use the public cloud for non-sensitive data and the private cloud for sensitive data.

Therefore, the cloud deployment model that can be shared by several organizations is the Community Cloud. In a community cloud, resources are shared by multiple organizations that belong to a specific community or group with common interests. The members of the community can share applications, services, and data on the community cloud while maintaining control and security over their respective data.
