A vApp is a container object composed of one or more component machines that can be provisioned and managed as a single entity.
vApps combine software-defined services when used with vRealize Automation to provide a single self-service portal for multiple provisioning platforms.
When you request a vApp from vRealize Automation, it provisions the vApp and its component machines in your organization's virtual data center. vRealize Automation manages the vApp as a parent and its virtual machines as children components in a similar manner to how it manages multi-machine services.
This relationship allows you to manage the vCloud Air or vCloud Director vApp by managing the vRealize Automation vApp. You can also perform operations directly on the individual component machines. For example, you can power off the vApp in vCloud Director by using machine actions in vRealize Automation. If you destroy a vApp machine and its component machines in vRealize Automation, you destroy the corresponding vApp and its component machines in vCloud Air or vCloud Director.
Tenant administrator or business group managers create vApp and vApp component blueprints. These blueprints specify the source vApp template from the vCloud Director endpoint or vCloud Air endpoint and define additional provisioning parameters to apply to the template. For example, additional storage volumes and capacity can be applied to a component blueprint which will be configured when the vApp virtual machine is provisioned in vCloud Director or vCloud Air.
In vRealize Automation, a vApp is a container for its component machines and is not a machine itself. The vApp is not counted as a machine in reports or licensing. For reporting and license purposes, vApp component machines are treated like any machine that vRealize Automation manages.
