On the vRealize Automation Host page, you set the base URL address for vRealize Automation. The address is usually the vRealize Automation appliance or, in high availability deployments, a load balancer.
When deploying only one vRealize Automation appliance with no load balancer, enter the vRealize Automation appliance FQDN. You can click to have the Installation Wizard populate the FQDN for you.
When deploying an enterprise configuration that includes one or more vRealize Automation appliances behind load balancing, enter the load balancer FQDN instead.
A single vRealize Automation appliance can still be deployed behind a load balancer. Taking that approach lets you add later appliances more easily, to expand the deployment.
