title: Amazon Route 53 green-blue deployment
body: <p>currently i am trying to implement green/blue deployment using AWS Route 53. There are simple web, rest applications which are run on custom EC2 instances, all behind Load Balancer. Web and rest are deployed are on same domain DNS.</p>
  
  <p>I would like to use Traffic Policy with weights (to have green blue deploys), as endpoint use different application Load Balancers (for green, blue). </p>
  
  <p>I wonder, is every request for same user always forwarded to the same Load Balancer? I don't want to end with situation where user gets webapp in old version and Api call is forwarded to new version.</p>
