Restricting data location to specific zones
Is it possible to impose a restriction that data belonging to specific account has to be stored in specific zone(s)?
A motivating example. Suppose a provider has servers in USA (zones 1-5) and Canada (zones 6-10). Let's imagine that a customer has some legal requirements to store its data on the servers in the USA. What I imagine doing is to restrict data for customer accounts to zones 1-5.
Is it supported in swift now? If not, are there other possibilities to restrict data location to specific servers?
