Same. I'm not clustered yet, but I plan on it before EOY and that would be amazing. I think route53 has some internal routing capabilities, but some of the setup looks scary, or am I just being silly?
just beware service discovery via DNS in AWS will return up to 8 addresses. so if you have more than 8 nodes you will get a random subsample for each request. depending on how your clustering works this may or may not be a problem. you can use the web api if you need to handle more than 8 hosts.
