Trick to keep in mind+3 XP
Law first, then latency, then price: a legal rule strikes regions off the list before any comparison.
Some data, such as health records, must stay inside a country or area. That is a constraint, not a preference, so it removes candidate regions before you weigh cost or fancy features. Among the regions that remain, those near your users give the fastest round trips. Involve compliance people first.
