An organization is evaluating options related to moving organizational assets to a cloud-based environment using an IaaS provider. One engineer has suggested connecting a second cloud environment…

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.

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.

A hosted hybrid cloud integrates a public or IaaS-based cloud service with a private cloud component that is hosted within the organization's own facilities or datacenter. In this scenario, the IaaS provider supplies the public cloud component, and the engineer's proposal to leverage the organization's existing datacenter space adds the privately hosted component. Together these form a hosted hybrid cloud, carrying risks related to managing and securing both environments simultaneously.

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.
