> 2.3. About Pods
> A pod often represents a single rack. Hosts in the same pod are in the same
> subnet. A pod is the second-largest organizational unit within a CloudStack
> deployment. Pods are contained within zones.
> Each zone can contain one or more pods. A pod consists of one or more
> clusters of hosts and one or more primary storage servers. Pods are not
> visible to the end user.
> [Pod is "third-largest" rather than "second-largest" now, after region and
> zone]
> 2.4. About Clusters
> ...
> A cluster is the third-largest organizational unit within a CloudStack
> deployment. Clusters are contained within pods, and pods are contained within
> zones. Size of the cluster is limited by the underlying hypervisor, although
> the CloudStack recommends less in most cases; see Best Practices.
> [cluster is the "fourth-largest" now]
> 2.7
> CloudStack provides plugins that enable both OpenStack Object Storage (Swift,
> swift.openstack.org1
> )
> and Amazon Simple Storage Service (S3) object storage. When using one of
> these storage plugins, you configure Swift or S3 storage for the entire
> CloudStack, then set up the NFS Secondary Staging Store for each zone. The
> NFS storage in each zone acts as a staging area through which all templates
> and other secondary storage data pass before being forwarded to Swoft or S3.
> The backing object storage acts as a cloud-wide resource, making templates
> and other data available to any zone in the cloud.
> "Swift" not "Swoft"
