Cloud Computing Deployment Models

                         Cloud

                     A cloud-based application is fully deployed in the cloud and all    parts of the application run in the cloud. Applications in the cloud have either been created in the cloud or have been migrated rom an existing Infrastructure   to take advantage of the benefits of cloud computing. Cloud-based applications can be built on low-level infrastructure pieces or can use higher level services that provide abstraction from the management, architecting, and scaling requirements of core infrastructure. 

 Hybrid

A hybrid deployment is a way to connect infrastructure and applications between cloud-based resources and existing resources that are not located in the cloud. The most common method of hybrid deployment is between the cloud and existing on-premises infrastructure to extend, and grow, an organization's infrastructure into the cloud while connecting cloud resources to internal system.

 

 On-Premise

    Deploying resources on-premises, using virtualization and resource management tools, is sometimes called “private cloud”.It does not provide many of the benefits of cloud computing but is sometimes sought for its ability to provide dedicated resources. In most cases this deployment model is the same as legacy IT infrastructure while using application management and virtualization technologies to try and increase resource utilization.
