Which of the following is a cloud computing deployment model that uses public resources on demand to extend its private infrastructure?
Hybrid is a cloud computing deployment model that uses public resources on demand to extend its private infrastructure. Hybrid uses a mixture of private and public infrastructure resources to form a single organization’s cloud.
There are four different cloud computing deployment models: private cloud, public cloud, hybrid cloud, and community cloud. Cloud computing is a term used to describe computing services that are offered for consumption in a way that demands fewer infrastructure expenses from the organization. Cloud computing deployment models describe how the cloud services are delivered to the customer. Cloud computing service models, on the other hand, describe the cloud services that the customer has purchased, such as infrastructure, platforms, or software.
Community is a cloud computing deployment model that can use a mixture of public and private infrastructure resources. However, community clouds share the public infrastructure resources between multiple organizations. Typically, the organizations involved in community cloud computing have common needs that the community cloud can provide.
Private is a cloud computing deployment model that is constructed for only the organization that uses its services. Private cloud computing is typically established by using either a third-party service or internal servers, not both. The use of a private cloud enables an administrator to ensure that the cloud’s resources are available only to an authorized few users.
Public is a cloud computing deployment model that is owned and operated by a service provider. Public cloud computing does not use a mixture of private and public infrastructure resources. Public clouds typically allow the general public to access storage and applications served from the cloud. For example, a Gmail account is a service that is provided from a public cloud. Other public cloud computing providers include Amazon and Rackspace.
