With the multi-machine services feature of vRealize Automation, users can provision multi-machine services, and their component machines, in a virtual datacenter based on existing templates.
Multi-machine services are compound services composed of multiple machines that can be provisioned and managed with vRealize Automation as a single entity.
For example, in a tiered application deployment, you might have multiple database servers, application servers, and Web servers. In addition to creating blueprints for each of the server types, you can also create a multi-machine blueprint that includes all of the machines needed for the entire application deployment. Users can then provision the multi-machine service and perform actions, such as rebooting, on all of the component machines with a single action.
