Data sovereignty is the idea that data are subject to the laws and governance structures of the nation where they are collected1 Data sovereignty issues can impact organizational initiatives that involve transferring or storing data across different jurisdictions, such as moving to a cloud-based environment. Cloud computing involves using remote servers and networks to store and process data, which may be located in different countries or regions with different data protection laws and regulations2 This can create challenges for organizations that need to comply with data sovereignty requirements of their own country or their customers' countries, such as data localization, data access, data security, data breach notification, etc3
