I wanted to ask about how one should go about choosing region for database / cloud provider when working on an application that stores user data for EU and US customers. Business behind the app is a EU registered company (Estonia).
To my understanding, it is easier and more future proof to store user data on EU servers, with Frankfurt being one of the top cloud provider locations.
Assuming that the way data is collected and stored is GDPR compliant, will there be any issues with US law and their citizen data stored in EU.
Data collected is not too private, mostly it consists of user emails and some profile data i.e images / descriptions / links to social media sites.
Another aspect here is to consider where majority of users are located to reduce network latency and it so happens that roughly 70% of our target market is in US, which means that storing data there would make more sense for better user experience, but in this case, what are some implications with storing EU user data on US servers?
