Elizabeth You can also use a simple "round robin DNS pattern" where the DNS server gives out the IP addresses of both ESB servers. However this has two big problems: 1. You don't get failover (if one server dies, requests still come to it). You can get round this using Linux tools like http://www.ucarp.org/project/ucarp
2. The load-balancing may be uneven between the two hosts due to DNS caching.
