title: power on vmware(vCloud) instance on demand
body: <p>We have several private vCloud vmware instances on which are deployed some java webaps. The instances are not corelated with each other.</p>
  
  <p>I am monitoring the usage of the apps and have some instances that are not used for days or even months. </p>
  
  <p>Is there a way maybe already built in vmware to stop the instance when not used for some days and to restart it fast when a new request comes in.</p>
  
  <p>The motivation for this is just to optimize wmware licence costs.</p>
  
  <p>I am already monitorng the requests to some instance and I know I could do ti thrugh vCloud Java api but I dont know if it would be fast enough to start the instance when a new request comes. </p>
  
  <p>Ahy hints in which direction should I go?</p>
