Well,
You would better consult with real-life mysql experts, as for me, I
referred to great severalnines.com articles like:

Hi,
Thanks again for the tips! Below is the current configuration, please
suggest changes if any.
HAProxy
frontend galera-fe
mode tcp
bind 10.231.4.112:3306
use_backend galera-be
backend galera-be
balance source
mode tcp
option tcpka
Sounds cool,
Just ensure that in any failure case (db, haproxy, OS or hardware crash)
all the Management servers are switched to the same Galera instance,
otherwise, this could lead to operational problems.
Also, backups are still mandatory, recommend doing them from one of
Galera's hot-swap nodes
Hi,
Thank you. Have set up MariaDB Galera Cluster with the required HAProxy
configuration with MYSQL health checks. Everything is working fine.

Hi, I use MariaDB Galera cluster.
But you have to pin all the CS management to the same galera node to make
cloudstack transactioned operations work correctly. HAproxy or shared
common ip solve that.
