hybrid cloud [English]
n. ~ A deployment model in which two or more clouds (private, community, or public) remain unique entities, but are connected by standardized or proprietary technology that enables data and application portability.
- Mell and Grance 2011 (†334 p. 3): 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).
- Duranti 2013 (†408 ): The most complex [deployment model] is the hybrid cloud, composed of two or more Clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability. (†485)
- Furht and Escalante 2010 (†583 p.339): A composition of the two types (private and public) is called a hybrid cloud, where a private cloud is able to maintain high services availability by scaling up their system with externally provisioned resources from a public cloud when there are rapid workload fluctuations or hardware failures. In the hybrid cloud, an enterprise can keep their critical data and applications within their firewall, while hosting the less critical ones on a public cloud. (†1148)
- McLelland, et al. 2014 (†403 7-8): The third type of cloud implementation that is available is a “hybrid” cloud. In this model, some of the infrastructure would be the shared space of the public model and some would be the isolated infrastructure of the private model. This model is appropriate when some client information is more sensitive, requiring storage in higher cost private space while less sensitive information can be kept in less expensive but more public space.

- Rackspace 2014 (†433 ): A hybrid cloud gives you the benefits of both public and private clouds. For example, you can put public-facing components in a public cloud, while storing customer-sensitive data in a private cloud. (†562)
- Stancic, Rajg, and Milosevic 2013 (†904 p. 111): The combination of two or more physical cloud infrastructures from different branches of the above listed deployment models that are physically separate but are connected via the means of mutual data and application portability or management hierarchies. (†2724)
- Wikipedia (†387 s.v. "Cloud computing"): Hybrid cloud is a composition of two or more clouds (private, community or public) that remain unique entities but are bound together, offering the benefits of multiple deployment models. Hybrid cloud can also mean the ability to connect collocation, managed and/or dedicated services with cloud resources. (†457)
