Before configuring, you must deploy virtual appliances to support vCloud Availability services.
You install all individual components of vCloud Availability by using the vCloud Availability Installer Appliance. The vCloud Availability Installer Appliance simplifies the installation by supporting a text registry file where all vSphere and vCloud Director details are stored.
There are two ways to deploy and configure vCloud Availability
You can use Full Commands Installation. The commands include addresses, user names, and the location of password files for all vCenter Server instances and vCloud Director hosts.
With Simple Command Installation you are using a vCloud Availability Installer Appliance registry. This way all vCenter Server and vCloud Director details are contained in a registry file.
Both ways to deploy and configure vCloud Availability are demonstrated for your reference.
You run all installation commands from the vCloud Availability Installer Appliance, unless documentation instructs otherwise.
