It would be useful if there was a glossary of terms related to Openstack. It is easy to get confused as many words are overloaded or slightly different between different parts of Openstack. There is also the page on identity at <http://docs.openstack.org/diablo/openstack-identity/admin/content/Identity- Service-Concepts-e1362.html> http://docs.openstack.org/diablo/openstack-identity/admin/content/Identity-S ervice-Concepts-e1362.html which defines some concepts. >From <http://wiki.openstack.org/Glossary> http://wiki.openstack.org/Glossary, there is a pointer to <http://cloudglossary.com/> http://cloudglossary.com/ but the openstack terms are not in there. There is also <http://docs.openstack.org/incubation/openstack-network/developer/quantum-ap i-1.0/content/Glossary.html> http://docs.openstack.org/incubation/openstack-network/developer/quantum-api -1.0/content/Glossary.html for networking.

Zones were a sharding scheme for Nova. Zones are being renamed to Cells to avoid further confusion. Availability Zones will remain the same. Hope it helps! -S _____ From: openstack-bounces+sandy.walsh=rackspace.com at lists.launchpad.net [openstack-bounces+sandy.walsh=rackspace.com at lists.launchpad.net] on behalf of Nicolae Paladi [n.paladi at gmail.com] Sent: Tuesday, March 20, 2012 6:55 AM To: openstack at lists.launchpad.net Subject: [Openstack] "nova zone" and "availability_zone" Hi all, What is the difference between "nova zone(s)" and "availability_zone"? 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?
