-- Stops a specified instance. When you stop a standard instance, the data disappears and must be reinstalled when you restart the instance. You can stop an Amazon EBS-backed instance without losing data. For more information, see <http://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-starting.html Starting, Stopping, and Rebooting Instances>.
