Druid Hybrid Cloud setup?

Anyone have experience or suggestions implementing Druid in a Hybrid cloud? I imagine this is largely no different other than underlying network if I were to add it to a different region in say AWS or GCP?

I’m just wondering what considerations / implications I would need to take into consideration?

Would ZooKeeper become a potential bottleneck or problem having to expose it over the webs.

What about the Coordinator?

Would standing up two separate clusters be the better alternative, and is there a good way to data sync either through ingestion tasks or what not?
