I love HAProxy so much. In our architecture, it started with simple frontend load balancing, but it ended up mediating almost every inter-server communication, which gave us a great amount of flexibility in swapping machines in and out, by giving each service load balanced virtual ip addresses. Thanks for your great work, Willy.
