A region is a general area, like eu-west, where a zone is similar to a datacenter. If a location has a parent, that implies it is within that location. For example a location can be a rack, whose parent is likely to be a zone.
    
    Specified by:
    
    listAssignableLocations in interface BlobStore

              CopyOptions options)
```
    Description copied from interface: BlobStore
