You configure load balancing for all services and components related to vRealize Automation and vRealize Orchestrator by using an NSX Edge load balancer. The load balancer is enabled when CMP fails over to Region B if Region A becomes unavailable in the event of a disaster or planned migration.

Configure the load balancer before you deploy the vRealize Automation appliance, because you need the virtual IP (VIP) addresses to deploy the vRealize Automation appliance.
