Data residency

Data residency is the location or jurisdiction where data is stored, processed, or replicated.

Data residency is the location or jurisdiction where data is stored, processed, or replicated. In manufacturing and industrial systems, it commonly refers to where production records, quality data, traceability records, technical data, supplier information, or system logs are hosted across cloud services, data centers, backups, and integrations.

Data residency matters when MES, ERP, PLM, QMS, historian, or supplier systems exchange data across sites, regions, or cloud environments. The term can apply to primary databases, replicated environments, disaster recovery copies, file storage, audit logs, and support-access workflows.

Data residency should not be confused with data sovereignty or data localization. Data sovereignty concerns the legal authority that may apply to data based on jurisdiction. Data localization usually refers to a requirement or policy to keep certain data within a specific country or region. Data residency describes where the data resides; by itself, it does not confirm access control, encryption, export-control handling, validation, or compliance status.

What is the ISO 27001 information security policy framework?

ISO 27001 provides a structured framework for an Information Security Management System (ISMS), including a hierarchy of policies, standards, procedures, and records. In regulated, brownfield manufacturing environments it must be tailored to legacy systems, validated tools, and existing QMS/IT controls, and it does not guarantee compliance or audit outcomes on its own.

How do ITAR and export controls affect digital instruction sharing with suppliers?

ITAR and export controls can restrict who may access digital work instructions, where the data may be stored, and how it may be transmitted to suppliers. The key issue is whether the instructions contain controlled technical data, which must be classified, access-controlled, version-controlled, and shared only through approved processes.

How should ITAR-controlled data be shared with aerospace suppliers?

Share ITAR-controlled data with suppliers only on a documented need-to-know basis, through approved channels, with access restricted to authorized parties and full traceability of what was shared, when, and under which revision. The right method depends on the data type, supplier status, contracts, system configuration, and how well access control, export review, and change control are implemented.

How should we handle export-controlled data within digital work instructions?

Export-controlled data in digital work instructions must be handled with the same rigor as in PLM/ERP: strict access control, environment segregation (e.g., GCC High/ITAR-safe), minimal exposure of technical details, and full traceability. The right approach depends heavily on your export control program, system stack, validation state, and data classification maturity.
