AWS Network Load Balancer
If you're curious to see NLB in action, here's a live demo: <a href="http://nlb-34dc3b430638dc3e.elb.us-west-2.amazonaws.com/" rel="nofollow">http://nlb-34dc3b430638dc3e.elb.us-west-2.amazonaws.com/</a> , it took about 5 minutes in the console to set it up and no changes on the targets/backends.<p>Massive disclaimer: I work on NLB.
