At Amazon Web Services, we’re committed to deeply understanding the evolving needs of both our customers and regulators, and rapidly adapting and innovating to meet them. The upcoming AWS European Sovereign Cloud will be a new independent cloud for Europe, designed to give public sector organizations and customers in highly regulated industries further choice to meet their unique sovereignty requirements. The AWS European Sovereign Cloud expands on the same strong foundation of security, privacy, and compliance controls that apply to other AWS Regions around the globe with additional governance, technical, and operational measures to address stringent European customer and regulatory expectations. Sovereignty is the defining feature of the AWS European Sovereign Cloud and we’re using an independently validated framework to meet our customers’ requirements for sovereignty, while delivering the scalability and functionality you expect from the AWS Cloud.

Today, we’re pleased to share further details about the AWS European Sovereign Cloud: Sovereign Reference Framework (ESC-SRF). This reference framework aligns sovereignty criteria across multiple domains such as governance independence, operational control, data residency and technical isolation. Working backwards from our customers’ sovereign use cases, we aligned controls to each of the criteria and the AWS European Sovereign Cloud is undergoing an independent third-party audit to verify the design and operations of these controls conform to AWS sovereignty commitments. Customers and partners can also leverage the ESC-SRF as a foundation upon which they can build their own complementary sovereignty criteria and controls when using the AWS European Sovereign Cloud.

To clearly explain how the AWS European Sovereign Cloud meets sovereignty expectations, we’re publishing the ESC-SRF in AWS Artifact including the criteria and control mapping. In AWS Artifact, our self-service audit artifact retrieval portal, you have on-demand access to AWS security and compliance documents and AWS agreements. You can now use the ESC-SRF to define best practices for your own use case, map these to controls, and illustrate how you meet and even exceed sovereign needs of your customers.

The ESC-SRF has been built from customer feedback, regulatory requirements across the European Union (EU), industry frameworks, AWS contractual commitments, and partner input. ESC-SRF is industry and sector agnostic, as it’s written to address fundamental sovereignty needs and expectations at the foundational layer of our cloud offerings with additional sovereignty-specific requirements and controls that apply exclusively to the AWS European Sovereign Cloud. Each criterion is implemented through sovereign controls that will be independently validated by a third-party auditor.

The framework builds on core AWS security capabilities, including encryption, key management, access governance, AWS Nitro System-based isolation, and internationally recognized compliance certifications. The framework adds sovereign-specific governance, technical, and operational measures such as independent EU corporate structures, dedicated EU trust and certificate services, operations by AWS EU-resident personnel, strict residency for customer data and customer created metadata, separation from all other AWS Regions, and incident response operated within the EU.

These controls are the basis of a dedicated AWS European Sovereign Cloud System and Organization Controls (SOC) 2 attestation. The ESC-SRF establishes a solid foundation for sovereignty of the cloud, so that customers can focus on defining sovereignty measures in the cloud that are tailored to their goals, regulatory needs, and risk posture.

The ESC-SRF describes how AWS implements and validates sovereignty controls in the AWS European Sovereign Cloud. AWS treats each criterion as binding and its implementation will be validated by an independent third-party auditor in 2026. While most customers don’t operate at the size and scale of AWS, you can use the ESC-SRF as both an assurance model and a reference framework you can adapt to your specific use cases.

From an assurance perspective, it provides end-to-end visibility for each sovereignty criterion through to its technical implementation. We will also provide third-party validation in the AWS European Sovereign Cloud SOC 2 report. Customers can use this report with internal auditors, external assessors, supervisory authorities, and regulators. This can reduce the need for ad-hoc evidence requests and supports customers by providing them with evidence to demonstrate clear and enforceable sovereignty assurances.

From a design perspective, you can refer to the framework when shaping your own sovereignty architecture, selecting configurations, and defining internal controls to meet regulatory, contractual, and mission-specific requirements. Because the ESC-SRF is industry and sector agnostic, you can apply criteria from the framework to suit your own unique needs. Depending on your sovereign use case, not all criteria may apply to your use case sovereign needs. The ESC-SRF can also be used in conjunction with AWS Well-Architected which can help you learn, measure, and build using architectural best practices. Where appropriate you can create your version of the ESC-SRF, map to controls, and have them tested by a third party. To download the ESC-SRF, visit AWS Artifact (login required).

The publication of the ESC-SRF is part of our ongoing commitment to delivering on the AWS Digital Sovereignty Pledge through transparency and assurances to help customers meet their evolving sovereignty needs with assurances designed, implemented, and validated entirely within the EU. Within the framework, customers can build solutions in the AWS European Sovereign Cloud with confidence and a strong understanding of how they are able to meet their sovereignty goals using AWS.
