At least people have asked me privately if these can be used in production, so I'll answer here - yes, while extensions are limited in functionality and supported lifecycles they can be used in production.
The in-built ones are meant to be supported across releases, and are not merely for demonstration purposes, and can be used as reference examples. We hope the extensions framework will allow more users to write their own custom extensions and solve their problems (in any language of choice). For example, bringing their brownfield deployments to CloudStack, adding support for bare metal and other hypervisors, Nutanix, OpenStack, public cloud (aws, gcp, azure etc), integrations (dbaas, marketplace, xaas...) and automation (storage, network switches etc). Future plans for the framework can include having support for console for supported protocols like vnc, new types of extensions and at some point, if the feature takes off, even a mechanism to have an extensions store that could allow users to publish their own or discover and use extensions created by others. Hope this helps. Regards.

The CloudStack integration with KVM also supports Ceph; you can introduce both "replicated" and "erasure code" pools to be consumed with RBD in ACS+KVM. Furthermore, you could also work with CephFS on ACS; you could mount the filesystem in a common directory in all the hosts and introduce it as a "SharedMountPoint" primary storage. There are plans to introduce CephFS as a protocol for primary storage in the future, similarly to NFS. However, the Ceph cluster is not managed by ACS, you must manage it (create the cluster, create the pools, configure the CRUSH rules, create the credentials, and so on) outside of ACS.
