title: How to disable Amazon EC2 charging?
body: <p>I currently try to implement amazon ec2 and I read that after one year they charge you. I used google app engine before(using java) and there is the feature that you can enable/disable charging. I just want to try the free ec2 instance, so here are my questions:</p>
  
  <ul>
  <li>Does Amazon EC2 AUTOMATICALLY charge you after one year?</li>
  <li>How to disable the automatically charging function?</li>
  </ul>
