Multi-machine services are containers for their component machines. Component machines can be virtual, physical, or cloud, or any combination of the three.

The following characteristics describe multi-machine services in vRealize Automation:

  • They are defined by a blueprint that references one or more component blueprints.

  • They can have a lease duration associated with them.

  • They are not counted as a machine in reports or licensing but their component machines are counted.

  • Requests can be made subject to approval.

  • Many machine operations, such as reboot, can be performed on the multi-machine service as a whole. The requested action is performed on all of the components in the service.

Some blueprint types, such as vCloud Director blueprints, cannot be added as components of a multi-machine blueprint.

These concepts apply to multi-machine services in vRealize Automation.

Component Blueprint

A machine blueprint that is part of a multi-machine service. A component blueprint is referenced by a multi-machine blueprint. You can also use it to request standalone machines that are not part of a multi-machine service.

Component Machine

A machine that is managed as part of a multi-machine service. A multi-machine service might include several component machines.

Multi-machine Blueprint

A blueprint that defines a multi-machine service.

Multi-machine Service

A compound service composed of multiple machines that vRealize Automation can provision and manage as a single entity.
