IMHO it does look like using ACS VPC might not be the best choice for  you.
I would rather look at an Advanced Zone with Security Groups and public IPs instead, if you
are happy to only have 1 network per VM or at Shared Networks.

Snapshots indeed are not the best way to do backups, I would advise using something specialised
such as Bacula or R1soft, inside the VMs.

I would still use ACS over XenCenter, mainly because it does add some nice things, such as
userdata, API and a certain hypervisor agnosticism, should you ever want to move away from
