System requirements for Service Management Automation

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.

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.
