Data residency.
also: data sovereignty · data localization · data localisation · data residency requirementsWhere data is physically stored and processed; residency rules require some data to stay within a country or region.
the two-minute refresher
- Residency = where data lives; sovereignty = whose laws apply; localisation = a legal requirement to keep it in-country.
- Architectures: one region (simple, can't comply), regional deployments (strong compliance, complex), or a global control plane with regional data.
- Assign each tenant a home region and route its data and processing there.
- Cross-border transfers need a legal basis such as SCCs.
