Actions represent the commands and requests that the users send to the vSphere environment to make changes to the virtual infrastructure.

All actions in the vSphere Web Client are governed by the Actions Framework. The Actions Framework determines which actions appear in the vSphere Web Client user interface, in toolbars and context menus. You can add actions to the vSphere Web Client by creating an extension to the Actions Framework.

When you create an action extension, you must also provide the ActionScript classes that are called when the user performs the action. You must also extend the vSphere Web Client service layer with a Java service. The Java service performs the action operation in the vSphere environment.
