Sovereign Cloud.
A cloud that not only resides locally in Australia, but is also owned, governed and managed locally, with controls in place to ensure customer, operational and management data is inaccessible to people outside Australia. It’s not even accessible by the cloud providers’ operational staff (contractors and foreign nationals), or accessible under foreign laws by non-Australian interests.
Clouds that are run/operated by non-Australians located offshore, even though an availability zone may exist within Australia, are not considered sovereign. Nor are clouds that are majority owned and controlled by non-Australian companies.
