Validate the Distributed Deployment
After deploying additional instances of the vRealize Automation appliance, you validate that you can access
the clustered appliances.
Procedure
1 In the load balancer management interface or conguration le, temporarily disable all nodes except
the node that you are testing.
2 Conrm that you can log in to vRealize Automation through the load balancer address:
hps://vrealize-automation-appliance-load-balancer-FQDN/vcac
3 After verifying that you can access the new vRealize Automation appliance through the load balancer,
re-enable the other nodes.
Install the IaaS Components in a Distributed Configuration
The system administrator installs the IaaS components after the appliances are deployed and fully
congured. 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
n
“Congure the Primary vRealize Automation Appliance,” on page 68.
n
If your site includes multiple instances of vRealize Automation appliance, “Add Another vRealize
Automation Appliance to the Cluster,” on page 72.
n
Verify that your installation servers meet the requirements described in “IaaS Web Service and Model
Manager Server Requirements,” on page 22.
n
Obtain a certicate from a trusted certicate authority for import to the trusted root certicate store of
the machines on which you intend to install the Component Website and Model Manager data.
n
If you are using load balancers in your environment, verify that they meet the conguration
requirements.
Procedure
1 Install IaaS Certicates on page 75
For production environments, obtain a domain certicate from a trusted certicate authority. Import
the certicate to the trusted root certicate store of all machines on which you intend to install the
Website Component and Manager Service (the IIS machines) during the IaaS installation.
2 Download the vRealize Automation IaaS Installer on page 76
To install IaaS on your distributed virtual or physical Windows servers, you download a copy of the
IaaS installer from the vRealize Automation appliance.
3 Choosing an IaaS Database Scenario on page 77
vRealize Automation IaaS uses a Microsoft SQL Server database to maintain information about the
machines it manages and its own elements and policies.
4 Install an IaaS Website Component and Model Manager Data on page 81
The system administrator installs the Website component to provide access to infrastructure
capabilities in the vRealize Automation web console. You can install one or many instances of the
Website component, but you must congure Model Manager Data on the machine that hosts the rst
Website component. You install Model Manager Data only once.
