Microsoft System Center Orchestrator is a workflow automation software product that allows administrators to automate the monitoring and deployment of data center resources.
Microsoft System Center Orchestrator was introduced as part of the Microsoft System Center 2012 suite as a rebranding of Microsoft’s previous workflow automation software, Opalis vNext. Orchestrator uses a drag and drop graphical interface to allow admins to define run books. Orchestrator translates these visual representations into .NET scripts, PowerShell or SSH commands to automate workflows. It is capable of managing multiple operating systems and can also handle VMware- and Citrix-based workflows.
Microsoft offers add-ons for System Center Orchestrator that extend its functionality, including the Microsoft System Center 2012 Orchestrator Integration Toolkit and the Microsoft System Center 2012 Orchestrator Integration Pack.
