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