For cloud - in particular Openstack (which I am working with ATM), the
biggest thing would be:
- multi-master replication
or failing that:
- self managing single master failover (voting/quorum etc)
Hmm.... consul (optionally in a dockerized setup) ?
https://www.consul.io/
There are already HA solutions based on consensus, like Patroni:
https://github.com/zalando/patroni
so that operators can essentially 'set and forget'. We currently use
Mysql+ Galera (multi master) and Mongodb (self managing single master)
and the convenience and simplicity is just so important (Openstack is a
huge complex collection of services - hand holding of any one
service is
pretty much a non starter).
Yes, I was also asked whether PostgreSQL has any optional
functionality like Galera Cluster for MySQL. He was planning a
scalable PaaS service which performs heavy reads and writes. Demand
exists.
AFAIK, Galera has its own set of drawbacks....
Right, some of them are explained here:
