# Recovery strategies to meet data residency requirements

## Summary

Organizations operating under data residency requirements must balance jurisdictional compliance with disaster recovery objectives for critical workloads on AWS. In locations served by a single Region or facing multi-Region constraints, three architectural patterns offer distinct trade-offs between regulatory adherence and operational complexity. The cryptographic boundary approach replicates encrypted data to another AWS Region while restricting decryption access using AWS Key Management Service policies. The data boundary pattern deploys AWS Outposts on-premises within the source country while relying on an external parent Region control plane. Finally, strict local autonomy boundaries retain data and control planes entirely in-country through on-premises systems or multi-cloud lifeboats, requiring rigorous end-to-end continuous testing.

## Context

Data residency mandates in regulated sectors and government agencies restrict where critical data and control planes can reside, creating challenges for disaster recovery when operating in countries served by only a single AWS Region.

## Approach / What changed

AWS outlines three disaster recovery architectures: replicating encrypted data across Regions with KMS policy locks, deploying AWS Outposts in-country with an external parent Region control plane, and implementing strict local autonomy via on-premises infrastructure or multi-cloud lifeboat environments.

## Takeaways

- A cryptographic boundary strategy replicates data across AWS Regions using AWS KMS keys configured with explicit deny policies to block recovery-Region decryption until authorized.
- AWS Outposts keep physical data in-country while utilizing a distinct parent Region control plane, but they require continuous network connectivity and support only a subset of AWS services.
- Strict local autonomy boundaries maintain both data and control planes inside national borders through on-premises hardware or multi-cloud lifeboat architectures, maximizing control at the cost of operational complexity.
