Zones are logical groupings of Nova Services and VM Hosts. Not all Zones need to contain Hosts; they may also contain other Zones to permit more manageable organizational structures. Our vision for Zones also allows for multiple root nodes (top-level Zones) so business units can partition the hosts in different ways for different purposes (i.e. geographical zones vs. functional zones). This proposal will outline our understanding of the issues surrounding Multi-Cluster and discuss some implementation ideas.
