What is Amazon S3 Files?

It's a new feature letting you mount S3 buckets as local POSIX filesystems on EC2, with 1ms access times—no SDK needed for file ops.

How do I use S3 Files with my apps?

Install the mount agent on EC2, run `s3fs bucket-name /mnt/point`, then use standard file APIs. Works with any language or tool expecting local disks.

Does S3 Files replace EBS or EFS?

Partially—for scratch and large datasets, yes. EBS for OS/boot, EFS for shared NFS. But S3 Files wins on cost and scale.
