Data Sovereignty and Residency: Jurisdictional Requirements, GDPR, and Multi-Region Architecture

Data Sovereignty and Residency#

Data sovereignty is the principle that data is subject to the laws of the country where it is stored or processed. Data residency is the requirement to keep data within a specific geographic boundary. These are not abstract legal concepts — they dictate where you deploy infrastructure, how you replicate data, and what services you can use.

Get this wrong and the consequences are regulatory fines, contract violations, and loss of customer trust. GDPR fines alone have exceeded billions of euros since enforcement began.
