At the annual Microsoft Management Summit, in March this year Microsoft announced that Opalis, which Microsoft acquired in December 2009, would be renamed to System Center Orchestrator.
System Center Orchestrator (SCO) is Run Book Automation (RBA) software, which can be used to define, build, orchestrate, manage and report on workflows. The workflows are defined in the SCO workflow designer, and so called Integration Packs are provided to interact with Microsoft and non-Microsoft products, which run on so called Action Servers.
