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 https://github.com/shapeblue/Trillian.
