Supporting every region in every public cloud infrastructure provider is absolutely the goal. But we can change the little widget to be less confusing, too.
I find this interesting. Do you plan to have every database record replicated across every one of your datacentres? That would be some crazy high availability.
Yes that is the model. Each region has a full copy of the data and has its own internal replication factor. The customer can select which cloud regions and providers to replicate to, and pay accordingly. So you will be able to choose how many replicas and where they are.
