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 on page 89
The backup Manager Service provides redundancy and high availability, and may be started manually
if the active service stops.
8 Installing Distributed Execution Managers on page 91
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 Conguring Windows Service to Access the IaaS Database on page 94
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 on page 95
After installation, the system administrator veries 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,” on page 91.
Install IaaS Certificates
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.
Prerequisites
On Windows 2012 machines, you must disable TLS1.2 for certicates that use SHA512. For more
information about disabling TLS1.2, see Microsoft Knowledge Base article 245030.
