vCloud Hybrid Service
VMware's vCloud Hybrid Service (vCHS) is an Infrastructure-as-a-Service (IaaS) solution that enables customers to use virtual networking to securely extend their existing Layer 2 / Layer 3 networks from the data center to the cloud-based vCloud Hybrid Service.
vCloud Hybrid Service is an extension of the company's private cloud-based vCloud Suite that was developed to help customers bridge their existing private cloud infrastructure to the public cloud. The vCHS and its virtual machines can be accessed, managed and migrated by VMware vSphere administrators from the vSphere client using the vCloud Connector plug-in.
The vCHS service is currently offered by VMware in two formats: a vCloud Hybrid Service Dedicated Cloud that provides physically isolated and reserved compute resources, and the less expensive vCloud Hybrid Service Virtual Private Cloud, which offers a multi-tenant compute resource model but with dedicated allocations for customers.
