Meteorhacks:Cluster to balance multiple instances of meteor services on aws

I used kadirahq/meteor-up to successfully deploy the same web services on two different AWS EC2 instances. ([login to view URL] is available upon request) I need to load balance incoming traffic to those web services using meteorhacks:cluster "already added" so that when one service goes down the other service continue to serve user's request. Currently the balancing is not happening. (AWS DNS records info is available upon request) Job is to achieve the Load Balancing and give instructions as to how to set it up on our AWS so that when requests are received by any instance of the cluster, the requests are shared among all instances to achieve equal load balancing.
