The system administrator installs the IaaS components after the appliances are deployed and fully configured. The IaaS components provide access to vRealize Automation Infrastructure features.
All components must run under the same service account user, which must be a domain account that has privileges on each distributed IaaS server. Do not use local system accounts.
Prerequisites
Configure the First vRealize Automation Appliance in a Cluster.
If your site includes multiple vRealize Automation appliances, Add Another vRealize Automation Appliance to the Cluster.
Verify that the server meets the requirements in IaaS Windows Servers.
Obtain a certificate from a trusted certificate authority for import to the trusted root certificate store of the machines on which you intend to install the Component Website and Model Manager data.
If you are using load balancers in your environment, verify that they meet the configuration requirements.
What to do next
Install a DEM Orchestrator and at least one DEM Worker instance. See Installing Distributed Execution Managers.
