4 Install an IaaS Website Component and Model Manager Data
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 configure Model Manager Data on the machine that hosts the first
Website component. You install Model Manager Data only once.
5 Install Additional IaaS Web Server Components
The Web server provides access to infrastructure capabilities in vRealize Automation. After the first
Web server is installed, you might increase performance by installing additional IaaS Web servers.
6 Install the Active Manager Service
The active Manager Service is a Windows service that coordinates communication between IaaS
Distributed Execution Managers, the database, agents, proxy agents, and SMTP.
7 Install a Backup Manager Service Component
The backup Manager Service provides redundancy and high availability, and may be started
manually if the active service stops.
8 Installing Distributed Execution Managers
You install the Distributed Execution Manager as one of two roles: DEM Orchestrator or DEM
Worker. You must install at least one DEM instance for each role, and you can install additional DEM
instances to support failover and high-availability.
9 Configuring Windows Service to Access the IaaS Database
A system administrator can change the authentication method used to access the SQL database
during run time (after the installation is complete). By default, the Windows identity of the currently
logged on account is used to connect to the database after it is installed.
10 Verify IaaS Services
After installation, the system administrator verifies that the IaaS services are running. If the services
are running, the installation is a success.
What to do next
Install a DEM Orchestrator and at least one DEM Worker instance. See Installing Distributed Execution
Managers.
Install IaaS Certificates
For production environments, obtain a domain certificate from a trusted certificate authority. Import the
certificate to the trusted root certificate store of all machines on which you intend to install the Website
Component and Manager Service (the IIS machines) during the IaaS installation.
Prerequisites
On Windows 2012 machines, you must disable TLS1.2 for certificates that use SHA512. For more
information about disabling TLS1.2, see Microsoft Knowledge Base article 245030.
