Data residency is the location where an organization’s data is physically stored and accessed, even if that data lives in the cloud. Companies that collect data from customers face a choice, or a mandate, that determines where they’ll keep their data in relation to where the data was actually collected. For example, an organization that gathers data from users in an EU member nation, such as Germany, will often store that data within Germany to comply with GDPR.
Data residency also includes provisions for handling data backups, restoration during failover, and other related forms of disaster recovery.
How does data residency work?
Data residency is an interesting concept due to data’s digital and nomadic nature. Data can travel and exchange hands across networks, national borders, and regional borders. This happens for a number of reasons, including the following:
Servers for a service are located in another country.
A company’s internal users (such as support or development) are in another country from where the service is hosted and data is replicated between them.
Organizations may be interested in selling and profiting from the sale of user data, the buyer of which may be based in another country or region.
Companies need to share internal data with external stakeholders or organizations, typically through a partnership or vendor services agreement.
Digital data still needs a brick-and-mortar home. Organizations using cloud databases powered by AWS, Digital Ocean, and others know that some of their data is stored in each vendor’s hardware-centric datacenters depending on the service used to store the data and its settings. The global distribution of these facilities can complicate management based on data residency rules and data sovereignty.
Storage location can impact whether or not authorities can legally access sensitive data, for any reason. And in some countries, a political regime’s or administration’s stances on data privacy can greatly impact a company’s storage practices. Customer demands for greater privacy and control can also influence where company data resides. Companies must often balance these demands with their own self-interests (or moral and ethical imperatives) while choosing to follow national residency laws. Data residency can therefore affect the following:
Data storage and processing practices, including targeted hosting provisions for unique territories and states (or equivalent)
Internal telemetry data handling for applications, APIs, and AI services
Cross-cloud or cross-border data transfers
Monitoring, incident reporting, and auditing
Access control and personally identifiable information (PII) management
Infrastructure-level security, encryption, and privacy measures
Overall, data residency practices exist in conjunction with data localization and data sovereignty requirements. While one category of data might come with laxer restrictions, other types of data are governed more tightly. Laws and regulations are also always evolving given the volatility of politics. Organizations must keep current with evolving data residency practices while closely inspecting how vendor service-level agreements (SLAs) can impact compliance.
What are the benefits of data residency requirements?
Various data residency practices and requirements can actually be advantageous for companies and their customers. Here’s how data management practices can help:
Customers gain transparency into where their data is stored and how organizations manage it.
Customers can get peace of mind by knowing their data flows are geographically limited.
Companies are incentivized to protect sensitive data while reducing its overall footprint, for both storage and security purposes.
The owners or providers of certain types of data are guaranteed easy access to the data important to them.
Organizations are held to stricter reporting standards while disclosing data breaches.
Compliant organizations can gain trust by handling data intelligently and ethically.
Despite these benefits, data residency is often complex. Navigating traffic flows across clouds, hybrid environments, and on-premises deployments requires organizations to carefully plan how they retain data. There are also latency concerns with serving data strictly from one specific location to distributed customers. It might also be harder to monitor data without proper automation or visibility across regions.

FAQs
Data residency is the physical location where an organization stores and accesses its data. Data sovereignty is broader and refers to the principle that data is subject to the laws of the country where it is stored or collected. Choosing where data resides is one way organizations meet their data sovereignty obligations.
