Load balancer

Hello :) I would like to implement a load balancer in Openlitespeed on 3 servers. I have 3 VPs servers and I think how to go about it, because the sites I have on the server are Wordpress (and therefore databases come into play). I understand that without replication of maria database load balancer there is no point? am I wrong? To ensure website stability.
Thank you for the reply. Yes, without database replication, the entire procedure in the case of Wordpress will not be successful.
Does the load balancer openlitespeed have any tests? Someone checked the efficiency of the solution in practice?
