both combined - any replication here is using mysql-ssl-encryption, even
between VM's on the same host because they may be splitted to different
hosts in case of VMotion

since i would never ever have listen MariaDB/MySQL the ssh-tunnel is
mandatory in any case or better if possible OpenVPN because the
encryption and HMAC-authentication of OpenVPN improves security
dramatical

have fun try to break that tunnel, you need the "ta.key" to even get any
package accepted, then ca.crt and client.crt and need to break DHE-AES

and since it's easy to setup MySQL replication with SSL *inside* that
tunnel it get wrapped - until today nobody on this planet can break
that all at once without a rootkit on the involved machines
