Availability zones allow you to indicate what group of physical hardware you would like your VM to run on. On East, West, and Graham clouds, there is only one availability zone, ''Nova'', so there isn't any choice in the matter. However, on Arbutus there are three availability zones: ''Compute'', ''Persistent_01'', and ''Persistent_02''. The ''Compute'' and ''Persistent'' zones only run compute or persistent flavors respectively (see [[virtual machine flavors]]). | Availability zones allow you to indicate what group of physical hardware you would like your VM to run on.

Using two persistent zones can present an advantage; for example, two instances of a website can run in two different zones to ensure its continuous availability in the case that one of the sites goes down. | ||
