Dns is not always a great solution if there are multiple A records. We wrote about a method for doing this with iptables and consul here.

I'm confused on why in your article, you say the setup doesn't use a load balancer. How is a dynamic reconfiguration of IPTables not the same as a load balancer? What happens when your iptables box dies?

Bc iptables would run locally on each server. So you would access localhost:8000 which iptables would auto load balance to the nodes consul had. There is no central iptables server

ah, some how that wasn't so clear. Clever idea, but how do you distribute load across your front-end servers (or whatever is your actual public facing service)? Do you still rely there on a load balancer or round-robin DNS? I guess I'd be concerned about how to scale those instances in response to demand..
