To scale out a multi-tenant VMware Aria Automation environment, use VMware Aria Suite Lifecycle.
Scaling out a tenant-enabled VMware Aria Automation from a single node to a three node cluster behind a load-balancer requires changes to its DNS and certificate requirements. Tenant enabled VMware Aria Automation can only be accessed through VMware Aria Automation tenant FQDNs. For more information on tenant FQDNs, see Multi-tenancy model for VMware Aria Suite Lifecycle products.
After scaled-out, VMware Aria Automation tenants must be accessed through load-balancer tenant FQDNs and DNS, and certificates changes must be made accordingly. The same recommendations are shown in the VMware Aria Suite Lifecycle user interface as a pre-requisite to be performed before scaling out VMware Aria Automation 8.x.
