title: Ensure free data transfer from S3 to EC2
body: <p><a href="http://aws.amazon.com/s3/pricing/" rel="nofollow">Amazon's pricing documentation</a> says </p>
  
  <blockquote>
    <p>"Data Transfer OUT From Amazon S3 To Amazon EC2 in the Northern Virginia Region (is) $0.000 per GB"</p>
  </blockquote>
  
  <p>Is there anything special I need to do to ensure that I don't get charged for transfers from S3 to EC2, assuming both are in the Northern Virginia Region? IE) Is executing a GET request from this EC2 instance to <a href="https://s3.amazonaws.com/" rel="nofollow">https://s3.amazonaws.com/</a>{bucketName}/{resource} going to automatically get counted as 'free' without doing anything additional? Or is there a private IP address for S3 that I need to access in this scenario?</p>
