Organizations are increasingly looking to automate administrators' daily lives. Microsoft and VMware responded with two key technologies: Windows PowerShell, which has become the preferred scripting language for Windows administrators, and VMware’s PowerCLI which provides a Windows PowerShell interface to the vSphere API. vSphere PowerCLI includes PowerShell Cmdlets, and documentation for administering vSphere components.
PowerWF combines both technologies into a single easy-to-use product that replaces legacy batch files, scripts and custom application development, enabling you to completely automate your vSphere environment without writing a single line of code. I created a little one minute Jing demo -how to build a PowerCLI Work Flow with PowerWF.
