I think the possibilities are huge with this area. I'd love to see more 'manager' layers that build on top of any 'cloud' system, even a local one, to give you a standard stack that is easy to move. Imagine something that lives at the hypervisor level (that you trust and was mature) taking control of your various cloud accounts to merge them and make it easy to migrate/leave one provider for another. I know that is the promise of terraform but we all want a good, consistent, interface to play with and then build the automation tools on top of. Maybe that is a good direction for proxmox? integrating with cloud providers in a seamless way. Anyway, a lot of promise in this area no matter the direction it takes.
