VMware vCloud Architecture Toolkit: Private VMware vCloud Service Definition
Cloud computing is an approach to computing that leverages the efficient pooling of on-demand, self-managed virtual infrastructure that is consumed as a service. The cloud computing approach - made possible by sophisticated automation, provisioning, management, and virtualization technologies - differs dramatically from the current IT model because it decouples data and software from the physical infrastructure that runs them. Cloud computing helps transforms IT from a cost center into a service provider. VMware vCloud is the VMware solution for cloud computing. This paper provides the service definition for an enterprise that provides private Infrastructure as a Service (IaaS) resources and uses public vCloud resources to extend its own private capacity.
