Perhaps thought should be given to other services besides Nova. Swift has no central
accounts database. For it to gather "all accounts like x" type queries, it'd
have to hit up every account node. Probably the same for a queue service. A database
service might have a central db, and I guess Nova has one. But, since not all do, there
has to be something external managing them, so why not have this something manage the
others as well?
For that matter there are proposals to distribute the DB for Nova as well.
Wouldn't it be good to have a Cloud Management Service that allowed you create
accounts, sub-accounts, users, groups, roles, projects, with linkages to
virtual machines, swift containers, queue service end points, etc.? Each new
service would just provide this management system an /account/grouping/resource
type url structure and not worry about all the rest.
"Keep it as simple as possible; but no simpler." Nova manages virtual machines
and their resources. Grouping such by account makes great sense, and maybe even by
project (I guess that's like a Swift container?). But that seems like more than enough
for a coding project.
'project' is nova's account construct. (If I had my druthers I'd rename
it to 'account', but that would take an annoying amount of refactor
work. )
