mysql replication using galera I want to learn how to use Galera cluster replication (MariaDB).  


Can anyone give an advice that I can start from specific point?
Is it compatible with vsphere?
For your first question:

Multiply Things you must know before using Galera Cluster.


Galera Cluster is not for scale write
Galera Cluster is not load balancer. It must integrate with HA Tools for this option
It's virtually synchronized Multi-master Replication
You need minimum of 3 nodes/servers(or 2 nodes and 1 abrirator)  to avoid split/brain.
You can't use MyISAM all of tables must be InnoDB.


So if you want to use Galera Cluster I thinks this article is good for start.
