Any image can be identical to cloud or local systems using virtualization.
It's simply a matter of experienced Linux administration supporting QA/DEV
and Production servers.
As a basic part of disaster recovery every server once built, hardened and
configured optimally needs to be imaged. Swap out of a waiting spare,
reimaging would be trivial to ensure uptime SLA.
That image can be used in Vmware, Xen or Citrix Xenserver VPS, depending on
your implementation and tools.
Next subject, of course would be disk SAN/NAS to manage large system file
sharing and DR images.
