I'm trying to understand how my load balance software does not become a single-point-of-failure. Do load-balancing software usually support failover/ha for themselves?

    They usually don’t, you dot hat by failover solutions on the machine (keepalived), virtualized or with the help of router/switch. It works best if no session state needs to be kept (this works well for cookie based sticky http sessions) – eckes Oct 14 '17 at 14:49

Ideally, you would use a pair of clustered load balancers in a active/passive failover configuration.


Yes, Traffic is configured to hit a Floating Virtual IP, when the master load balancer fails the slave detects this, brings up the Floating IP and sends a load of gratuitous ARPs to the network. You can achieve this with VRRP, Keepalived, CARP etc. The Loadbalancer.org appliances use HA-Linux & HAProxy.
