The full answer
Data residency requirements come from regulation, sector rules, government and enterprise customers, or simply your users' expectations. We confirm them during discovery so the hosting region is part of the architecture from the start, not a migration later.
Hosting in a region covers more than the main database. Backups, file storage, logs, search indexes and analytics can all hold personal data, so we keep each of them in the chosen region where required and document where data flows.
Some third-party services, including certain AI models and email or analytics tools, process data in other countries. We flag these, choose regional options where they exist, or design the product so sensitive data does not reach them.
For products serving several markets, we can design a multi-region setup that keeps each market's data in its own region. Infrastructure is managed as code with tools such as Terraform, so environments are consistent and auditable.
We also plan disaster recovery within your residency constraints, for example by replicating backups to a second region in the same country where the cloud provider offers one. That way resilience does not come at the cost of moving data somewhere it should not go.
