VMware vCloud Hybrid Service (vCHS)

VMware vCloud Hybrid Service (vCHS) is an Infrastructure as a Service (IaaS) offering based on the VMware vSphere hypervisor.

vCHS features three IaaS services -- dedicated cloud, virtual private cloud and disaster recovery as a service (DRaaS). The dedicated cloud offering, which is intended for large cloud projects with resource-intensive workloads, provides 120 GB of vRAM, 30 Ghz vCPU and 6 TB of storage. It allocates a 50 Mbps network by default and can burst up to 1 Gbps in times of increased demand. VMware dedicated cloud physically isolates the servers for each customer's infrastructure, which may be a requirement for businesses in regulated industries.

In contrast, the vCHS virtual private cloud service relies on logical separation in a Multi-tenant environment. It  features 20 GB of vRAM, 5 GHz vCPU (which can burst to 10 GHz) and 2 TB of storage. Its default network allocation is 10 Mbps, with bursts up to 50 Mbps.

The DRaaS offering, which was first made available in April 2013, is based on the VMware vSphere Replication toolset. The vCHS DRaaS replicates VMs to vCHS servers and runs them from the cloud if the local instance fails. The DRaaS offering features 20 GB of vRAM, 10 GHz vCPU and 1TB of storage.

All three vCHS services can be managed with vCenter, vCloud Automation Center or vCloud Director.
