we are working on migration of our stack to Hetzner Cloud and trying to figure out the way to separate our dev/monitoring/prod resources across multiple projects/accounts in order to have fine grain access management and isolation. We are struggling to find an option that would allow us to connect private networks from either multiple projects belonging to the same account or multiple accounts.
We have checked out vSwitch option, however it won't allow connection of multiple cloud networks. Any hint or advice is highly appreciated. So far we can't see any option but putting all the resources under same account, project and network within it.
