title: Would creating an Amazon ELB affect running instances?
body: <p>I have several Amazon instances running my company's websites in the default VPC. I want to create an Internet-facing load balancer and add new instances under it for the given VPC.</p>
  
  <p>My question is would the creation of a new ELB affect request routing to my old instances unless I add them explicitly. </p>
  
  <p>I am afraid that my websites would go off-line in the case I misconfigure ELB.</p>
