How to: Redundant load balancers
As you must've already guessed, the load balancer itself can be a single point of failure. To overcome this, a second or `N` number of load balancers can be used in a cluster mode.

And, if there's a failure detection and the _active_ load balancer fails, another _passive_ load balancer can take over which will make our system more fault-tolerant.
