Data residency is the requirement or preference that data be stored in a specific geographic location or region. It matters because where data physically or logically resides can affect legal obligations, latency, operational control, and privacy expectations.
What is Data Residency?
Residency programs often appear in cloud architecture, regulated workloads, customer contracts, and regional platform design. They influence hosting decisions, backup location, failover design, and vendor selection.
What Data Residency Commonly Supports
Common uses include regional cloud deployment, regulated hosting, customer assurance, and transfer-control strategy.
Data Residency vs. Unrestricted Geographic Storage
Residency imposes location-aware placement rules. Unrestricted storage allows data to move or be stored wherever the platform chooses.
Frequently Asked Questions
Why is residency different from sovereignty?
Residency is about physical or regional location. Sovereignty is about which legal authority governs the data.
Does residency solve every compliance issue?
No. Access, transfer, subprocessing, and jurisdictional authority still matter too.
