Addressing Data Residency with AWS

Whitepaper image

AWS has released a new whitepaper that has been requested by many AWS customers: AWS Policy Perspectives: Data Residency. Data residency is the requirement that all customer content processed and stored in an IT system must remain within a specific country’s borders, and it is one of the foremost concerns of governments that want to use commercial cloud services. General cybersecurity concerns and concerns about government requests for data have contributed to a continued focus on keeping data within countries’ borders. In fact, some governments have determined that mandating data residency provides an extra layer of security.

This approach, however, is counterproductive to the data protection objectives and the IT modernization and global economic growth goals that many governments have set as milestones. This new whitepaper addresses the real and perceived security risks expressed by governments when they demand in-country data residency by identifying the most likely and prevalent IT vulnerabilities and security risks, explaining the native security embedded in cloud services, and highlighting the roles and responsibilities of cloud service providers (CSPs), governments, and customers in protecting data.

Large-scale, multinational CSPs, often called hyperscale CSPs, represent a transformational disruption in technology because of how they support their customers with high degrees of efficiency, agility, and innovation as part of world-class security offerings. The whitepaper explains how hyperscale CSPs, such as AWS, that might be located out of country provide their customers the ability to achieve high levels of data protection through safeguards on their own platform and with turnkey tooling for their customers. They do this while at the same time preserving nation-state regulatory sovereignty.

The whitepaper also considers the commercial, public-sector, and economic effects of data residency policies and offers considerations for governments to evaluate before enforcing requirements that can unintentionally limit public-sector digital transformation goals, in turn possibly leading to increased cybersecurity risk.

AWS continues to engage with governments around the world to hear and address their top-of-mind security concerns. We take seriously our commitment to advocate for our customers’ interests and enforce security from “ground zero.” This means that when customers use AWS, they can have the confidence that their data is protected with a level of assurance that meets, if not exceeds, their needs, regardless of where the data resides.
