The scenario is, I have two web servers both are running Nginx on it. Also I have configured HAProxy after the LB (load balancer) for both the servers. I've checked with Heartbeat, but no luck to make downtime count zero. I want some application which will switch to secondary server instantly when primary server goes down, in other words it should not give any downtime.
How to get zero downtime on HAProxy with a load balancer configuration?
heartbeat;haproxy
