title: How can one determine the current region within an AWS Lambda function?
body: <p><code>Regions.getCurrentRegion()</code> returns null from within an AWS Lambda function.  It seems that <code>Regions.getCurrentRegion()</code> is not supported from within an AWS Lambda function.  Is there an alternative way to determine which region the lambda function is running in?</p>
  
  <p>NOTE:  AWS Lambda function is written in Java.</p>
