Hi Jay,

Don’t think anyone is working on this, most people in the CloudStack community 
run on premise. You also have to take into account what kind of networking is 
on offer from Google, AWS and so on. If you ran your guest isolation over 
Layer3 (i.e. basic zones and possibly some SDN overlay) you may get this to 
work – but you would still have to take control of the IP ranges being offered 
in each Google/AWS availability zone such that you could consume these in the 
nested CloudStack environment. Layer2 advanced zones (VLANs) is probably going 
to be a big no-no, I can’t see any cloud provider letting you have control of 
L2 unless you have dedicated networking (e.g. Direct Connect?). 

So – ultimately if you can get network isolation to work with what’s allowed 
within the framework of AWS VPCs or the Google networking equivalent – then you 
may have a chance, if not you’re going to struggle. I would suggest you start 
with basic zones and see how you get on.

Obviously, I’m happy to be proven wrong on this – if you find a solution then 
please let the community know.

On a sidenote – a few people in the community now run our Trillian framework – 
which allows you to run nested CloudStack within CloudStack (all on premise) as 
long as the top layer hypervisor is VMware – more info on

    And if there is no usecase for it, someone better tell the vendors who
    are supporting it!  Quite a few now -- google is not the first.  AWS
    does it via a third party.  I have used skytap for training
    purposes....  etc...
