You can deploy multiple instances of the vCenter Server Appliance or the Platform Services Controller concurrently (in batch mode) using the CLI installer.
To deploy multiple instances concurrently, create JSON templates for all the vCenter Server Applianceand Platform Services Controller instances in your deployment. The CLI installer assesses the topology of the deployment using the JSON templates, and determines the order. For this reason, the JSON templates must use static IP addresses for all vCenter Server and Platform Services Controller instances in the deployment that are dependant upon one another. For example, you can install two vCenter Server instances which share a common external Platform Services Controller instance.
To perform the batch deployment, place the JSON templates defining your deployment in a single directory. When invoked, the CLI installer deploys your existing deployment using the topology defined in the JSON templates.
