Amazon S3 Files Release

S3 Files delivers a shared file system that connects any AWS compute resource directly with your data in Amazon S3. It provides full file system semantics and low-latency performance, without your data ever leaving S3. File-based applications, agents, and teams can now access and work with your S3 data as a file system using the tools they already depend on.

S3 Files eliminates the need to duplicate your data or cycle it between object storage and file system storage. It maintains a view of the objects in your bucket and translates file system operations into efficient S3 requests. Your file-based applications run on your S3 data with no code changes, and ML teams can run data preparation workloads without duplicating or staging files first.

S3 Files is now generally available in 34 AWS Regions. For the full list of supported Regions, visit the AWS Capabilities tool.
