Hybrid Cloud Computing Deployment Model

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 are increasingly being used by corporations where there is a need to maintain some of their applications on their internal infrastructure because of regulatory compliance or due to sensitivity of data, but also need the scalability and cost benefits of the public cloud.The most correct definition of the term “Hybrid Cloud” is probably the use of physical hardware and virtualized cloud server instances together to provide a single common service.But in most cases hybrid cloud is a combination of private and public cloud.

By utilizing "hybrid cloud" architecture, companies and individuals are able to obtain services with fault tolerance combined with immediate usability without depending on the internet connectivity.Cloud bursting is the term normally used for this type of environment where internal applications are deployed on private cloud for normal usage while internet applications are deployed on the public cloud to handle variable loads.Hybrid cloud architecture requires both on-premises resources and off-site (remote) server-based cloud infrastructure.

Hybrid cloud provides the flexibility and security of in house applications with the fault tolerance and scalability of cloud based services.Two clouds that have been joined together are more correctly called as a “combined cloud”
