AWS Launches S3 Files for Shared Bucket Mounts

AWS launched S3 Files, letting teams mount existing S3 buckets as shared file systems without moving the data out of S3 first. AWS says the feature is built using EFS and targets file-based apps, agent pipelines, and ML prep jobs that normally force awkward copies between object storage and separate file systems. It is a meaningful shift in how S3 can be used, and the early discussion immediately zeroed in on the usual hard parts of distributed file semantics.
