Amazon S3 adds compute checksum to verify datasets

🔒 Amazon Web Services has added a compute checksum operation to S3 Batch Operations, enabling large-scale verification of stored datasets without restoring or downloading objects. You can submit a manifest or target a bucket with prefix/suffix filters, select algorithms such as SHA-256, MD5, CRC32C and others, and receive a detailed integrity report when the job completes. This capability complements S3's built-in validation and simplifies compliance, preservation, and accuracy checks across all storage classes and object sizes.

Amazon S3 Express One Zone adds FIS resilience testing

🛠 AWS now supports resilience testing for S3 Express One Zone using AWS Fault Injection Service (FIS), enabling simulated network disruptions that cause data plane requests to timeout for directory buckets. The FIS network disruption action is included in the AZ Availability: Power Interruption scenario and is available in all Regions where the storage class is offered. You can run experiments via the AWS Management Console, AWS CLI, or the FIS API to validate monitoring, recovery procedures, and improve application resilience; consult FIS pricing for cost details.
