Explanation
Combining an external IaaS provider with a private cloud hosted in the organization's own datacenter facilities describes a hosted hybrid cloud model.
Common mistakes.
- A. A hybrid cloud is a general term for any combination of two or more cloud environments; it does not specifically capture that the private component is hosted within the organization's own facilities alongside an external IaaS provider.
- B. An on-premises private cloud is a single cloud environment built and managed entirely within the organization's own datacenter, with no connection to an external IaaS provider.
- D. A private cloud is dedicated to a single organization and does not incorporate the public IaaS component already in use by the organization in this scenario.
Concept tested. Cloud deployment model identification - hosted hybrid cloud
