Data Residency Basics for Global Teams

By Felix Adler · June 30, 2026 · Compliance

Data residency questions arrive late in most projects, usually phrased as: can you just keep EU customer data in the EU? The honest answer is that 'just' is doing enormous work in that sentence, because residency is not a hosting decision but an architecture decision.

The trap is assuming a region pin on your primary database solves it. Backups, search indexes, analytics exports, email logs, and crash reports all replicate data, often across borders by default. Auditing those paths is most of the actual work.

Teams that handle this well treat residency as a routing property: requests are geolocated at the edge and pinned to a jurisdiction-aware stack end to end. It is more infrastructure than anyone wants, but it is less than a regulator finding your analytics pipeline.
