For this reason, Openstack clouds can be divided in three main hierarchical zones: Regions, Availability Zones and Host Aggregates. The ID of network this Interface belongs to. You can request a specific AZ when you create or modify a Single-AZ instance, and you can use more-specific DB subnet groups for Multi-AZ instances. Copied to Clipboard. Contrast aggregates with availability zones (AZ) in OpenStack, which are customer-facing and usually partitioned geographically. Install the Ceph client used by Glance.
