Availability Zone is an EC2 concept. Zones were a sharding scheme for Nova. Zones are being renamed to Cells to avoid further confusion. Availability Zones will remain the same.

In a new deployment, the *services* table in the nova db contains an "availability_zone" column (which is 'nova', but default). If that is not the same as "nova zones" (which are logical deployments, as far as I understood), where is information about zones stored? The only documentation about "zones" in openstack that I could find is here: http://nova.openstack.org/devref/zone.html is there anything on availability zones? Cheers, /Nicolae.
