title: Understanding AWS data transfer cost (EC2-ELB)
body: <p>I have two EC2 instances behind one Classic Load Balancer.</p>
  
  <p>I have one domain (example.com) which points to ELB.</p>
  
  <p>I have the traffic coming from web client as well as from within my application.</p>
  
  <p>I want to understand if I make a call (in code) from EC2 instance to example.com, 
  what will be the data transfer cost for such calls?</p>
  
  <p>i.e. will this be considered as Internet Outbound Transfer or Within VPC transfer?</p>
