We have been requested interally many times on how we can deploy VMware Aria Automation Orchestrator without VMware Aria Automation.
There are still many customers who have first started using Automation Orchestrator and end up with Automation Orchestrator as their main automation engine.
For them it was really difficult visualize Automation and Automation Orchestrator is the only way to deploy via Suite Lifecycle.
Now, we got this sorted out. This is really a happy moment for us to share with you, that you can deploy Automation Orchestrator ...with Automation ...using Suite Lifecycle and can do complete Lifecycle management..as any other Suite Lifecycle integrated product
In this example , i have following versions being deployed.
VMware Aria Suite Lifecycle 8.12
VMware Aria Orchestrator 8.12I'll be creating a new environment to install product "VMware Aria Automation Orchestrator 8.12 with vSphere Authentication"
Agree EULA
Select appropriate certificate created for this installation
Select appropriate infrastructure configuration for this installation
Input appropriate network details
Just before i go to the next screen , i'd like to state that there's a AD group which was created to be used during vSphere Authentication during Automation Orchestrator deployment. This is the admin group.
Now , going ahead with the Suite Lifecycle product creation flow and entering required information of the product
Prechecks in progress and everything is successful
Review and Submit the request
Request is now submitted and deployment is in progress
Appliances deployment on vCenter
Request in progress and after 43 minutes it completes the deployment of the VMware Aria Automation Cluster version 8.12
Exploring environment details
As we can see in the screenshot below
Authentication Type is set to vSphere, as we deployed a vSphere authentication based VMware Aria Automation Orchestrator cluster 
On the load balancer end , you can see the pool is up
Accessing the cluster with it's VIP works.
One cannot access VMware Aria Automation Orchestrator page per node basis you would get a 404 not found exception.
