[openstack-dev] [all] [cross-project] Any Openstack partitioning movements in this summit?

Nova cell has emerged for several release cycles, with the mission of
scalability. Now there are claims of Neutron cell. Maybe similar
Cinder/Ceilometer partition demands would appear in the future.

So I wander if cross-project Openstack partitioning would go into the
our sight in the near term, with the following topics for example:

a) Any other value for partitioning besides scalability? e.g. fault
domain isolation, heterogeneous integration...
b) Which projects need partitioning besides Nova?
c) Standalone partition design and deploy for each project, or some
collaboration is need across them?  e.g. Can a host belong to one Nova
partition and another Cinder partition?
d) Concept clarifying and instructions on different partition
granularity, e.g. Cell, Available Zone, Aggregator...
e) Interface choice between parent and child partitions, internal RPC
or external REST, or some other protocols?

Best Regards
