No - in fact, it merely introduces another single point of failure,
which I assume is what you want to avoid. However, you need *something*
that will choose whether the primary or standby instance receives any
given request from the user. You could use any appropriate approach -
changing IP addresses, one or more front-end gateways that detect failed
requests, whatever meets your requirements.
