Thanks a bunch.
We have 5 web servers hosting the same website, they are duplicates of each other. We also have an F5 in front of them to balance the traffic.
The database the customer picked is MariaDB, but they want it behind the firewall and they also want high availability. In the scenario you described with a primary and a failover DB Server , the failover must be seamless to the web servers. So all the 5 WP web servers must point to a primary DB, which replicates to the failover DB and then I must come up with a mechanism to automatically switch the servers in case the primary fails.
I know SQLServer has mirroring and witnessing tools. But not sure about MariaDB.
