I would like to setup a fault-tolerant web-service. I will build the web-service with Erlang/OTP. At the beginning the web-service will be hosted on a few VPS. Each VPS has its own IP-address, and I can use more if IPs if I need.

I would like to have the domain name pointing to a single IP-address. How can setup my Erlang/OTP-application to be fault-tolerant behind a single IP-address?

Do I need to use VLAN? Is there a way my Erlang/OTP-application can use heartbeats and handle virtual IP-addresses to route the traffic? or how should I solve this problem?
