title: automatically start an EC2 instance when a request is made
body: <p>I have website that I access very infrequently (sometimes 2/3 times a day and sometimes none)</p>
  
  <p>I would like to automatically shutdown the instance as soon as no traffic happen (this would be possible when setting a cloudwatch alarm).</p>
  
  <p>The current issue I have is that I would like to start the instance again as soon as there is a request on the website (I don't mind at all having to wait for the instance to come back online).</p>
  
  <p>Is there any way of doing that? If yes how would that work technically?</p>
