Don't get me wrong. I love me some Galera. :) However, what the poster 
is really working towards is an implementation of the VCPE and eVCPE use 
cases for ETSI NFV. These use cases require a highly distributed compute 
fabric that can withstand long disruptions in network connectivity 
(between POPs/COs and the last mile of network service) while still 
being able to service compute and network functions at the customer premise.

Galera doesn't tolerate network disruption of any significant length of 
time. At all. If there is a Keystone services running on the customer 
premise that is connecting to a Galera database, and that Galera 
database's connectivity to its peers is disrupted, down goes the whole 
on-premise cloud fabric. And that's exactly what I believe the original 
poster is attempting to avoid. Thus my not understanding the choice here.

Best,
