title: Can multiple EC2 workers "utilize" the same IP address?
body: <p>The setup:</p>
  
  <ul>
  <li>SQL for queueing jobs</li>
  <li>EC2 workers for running jobs (autoscaling via CloudWatch)</li>
  </ul>
  
  <p>The problem:</p>
  
  <p>As jobs are run, many of them require connecting to third-party systems that have very strict security policies.  As such, the only way to access these systems is by white-listing our worker's IP address in advance.  However, as new EC2 instances spin up they will (obviously) have different IP addresses.</p>
  
  <p>What would it take to make all the workers' requests come from a single, static IP address? I don't see anything in AWS that covers this.</p>
