Updated: May 13, 2016
Applies To: Windows Azure Pack for Windows Server, System Center 2012 R2 Orchestrator
This topic describes the minimum hardware and software configurations that are required for a full installation of Service Management Automation.
Hardware requirements
The following recommended configurations should be used.
| Performance component | Recommendation |
|---|---|
| Virtual machines | Three, each with a runbook worker and web service installed Load-balanced incoming traffic Minimum of two cores and 4 GB of RAM for each virtual machine 60 GB of available disk space |
| SQL Server | One computer with 8 GB of RAM and eight cores Note: One month of data under heavy load (12 jobs per minute for a month) results in 20 GB of disk space usage. Job purging should be used to keep this usage from growing beyond this amount. |
Software requirements
The following software must be installed for each role.
| Role | Prerequisites |
|---|---|
| Runbook worker | Windows Server 2012 R2 Windows PowerShell 4.0 |
| Automation web service | Windows Server 2012 R2 SQL Server 2012 (not Express edition) Internet Information Services (IIS) 7.5 (hosts the web service) IIS Basic Authentication IIS Windows Authentication IIS URL Authorization ASP.NET 4.5 .NET Framework 3.5 (for the Setup program) .NET Framework 4.5 WCF HTTP Activation |
| Windows PowerShell module | Windows PowerShell 4.0 |
Before installing the web service, use the following procedure to install .NET Framework 4.5 and HTTP Activation on Windows Server 2012 R2:

Click Next, and follow the prompts to finish the installation.
Running Service Management Automation on Windows Azure virtual machines
Service Management Automation runs on Windows Azure just as it does on physical computer systems.
Service Management Automation was tested by Microsoft by installing and using it in a Windows Azure virtual machine. The testing concluded that Service Management Automation was fully functional and operated exactly the same as it does on physical hardware. Stability and performance benchmarks inside a Windows Azure virtual machine were at a level where no special considerations were needed.
Security Requirements
The following ports must be opened for each role.
| Role | Requirement |
|---|---|
| Runbook worker | None |
| Automation web service | Default value: 9090. Configurable at install time port defaults to 9090. The installation program for Service Management Automation automatically opens the web service port on the local firewall. |
| Windows PowerShell module | None |
The following certificates are required for each component.
| Role | Requirement |
|---|---|
| Runbook worker | None |
| Automation web service | A certificate that can be used for Secure Sockets Layer (SSL) encryption over HTTPS. The installation program for Service Management Automation can be used to generate a self-signed certificate. |
| Windows PowerShell module | None |
