With the many existing cmdlets designed for the system administrator or vSphere Admin, PowerCLI is the easiest and most powerful tool for managing your environment.
Onyx for the Web Client
Onyx for the Web Client is a Fling that translates actions taken in the vSphere Web Client to PowerCLI.Net code. This Fling was the winning entry in last year’s 2014 Fling Contest. It’s an update, of sorts, to the Onyx fling, as it allows for similar functionality in the web client.
