Since service list is the first step it's id defines the order and not the zone name. Availability Zones are an end-user visible logical abstraction for partitioning a cloud without knowing the physical infrastructure. For instance, if some customers need really fast VMs you can host them on your super expensive compute rack full of SSDs.Then what you can do is boot all the instances of your customer that way: Both hypervisors have access to shared storage. Required extensions Nova AZs can be matched with MAAS zones depending on how options default-availability-zone and customize-failure-domain are configured. cloudpipe-create In Openstack we can accumulate multiple Compute nodes and create a host aggregate. Availability zones are not modeled in the database; rather, they are defined by attaching specific metadata information to an aggregate The addition of this specific metadata to an aggregate makes the aggregate visible from an end-user perspective and .
