  • Data Sovereignty question and S3 Cross-Region Replication (CRR) / Same-Region-re

    Question: “A financial company has an Amazon S3 bucket that is used as a data lake for various cryptocurrency data sent from crypto exchanges across the globe. The DevOps team notices inconsistencies in data upload times across different regions. The company aims to guarantee high availability and fast access to the S3 bucket data across all regions as well as ensure data sovereignty. The challenge lies in accomplishing these objectives with minimal management overhead.”

    The answer is presumably “Enable S3 Transfer Acceleration on the bucket and use S3 Cross-Region Replication (CRR) to replicate the data to buckets in each region.” And one of the explanations for why it is: “It (S3 Cross-Region Replication (CRR) also addresses the requirement of data sovereignty, as data is stored within the specific regions where the company operates.” but I don’t believe this is accurate – or I think it’s misleading as data sovereignty is all about keeping data in the same region or at least in the same country. In fact, one of the links under References https://medium.com/cloud-techies/s3-same-region-replication-srr-and-cross-region-replication-crr-34d446806bab discusses data sovereignty but refers to same region replication, not cross-region.

    Hi or-3,

    Thank you for your feedback.

    Yes, you are correct about that part of DataSoverinty. However, “other data Sovereignty paradigms seek to make sure that the legal protections guaranteed to data generated in a jurisdiction will follow the data even if it is processed or stored in another jurisdiction.”-(https://www.cloudflare.com/learning/privacy/what-is-data-sovereignty/#:~:text=The%20term%20%E2%80%9Cdata%20sovereignty%E2%80%9D%20refers,the%20laws%20of%20that%20location.)
    While Amazon S3 CRR is not inherently designed solely for data sovereignty compliance, it can be part of a broader compliance and data management strategy that respects and adheres to such laws while still leveraging the benefits of geographical data replication.

    I understand that the explanation may not have been clear, and I apologize for any confusion it may have caused.

    Again, thank you very much for your feedback and rest assured, we will use your feedback to further improve our explanations.

    Neil @ Tutorials Dojo
