AWS Launches Amazon S3 Files for Bucket Access

Amazon Web Services launched Amazon S3 Files on April 7, introducing a new file system interface that enables applications and AI agents to access data stored in S3 buckets as if they were using a traditional file system. The feature, built on Amazon Elastic File System technology, is now generally available in 34 AWS regions worldwide, including several in Europe such as Frankfurt, Ireland, London, and Paris.

S3 Files addresses a long-standing challenge in cloud storage: the mismatch between S3's object-based architecture, which excels in scalability and cost-effectiveness for large-scale data lakes, and the file-based access patterns required by many tools, libraries, and workflows. Previously, organizations often had to duplicate data to a separate file system or create complex synchronization pipelines to make S3 content accessible to file-oriented applications, leading to added latency, inconsistency, and operational overhead. With S3 Files, users can mount an S3 bucket via an NFS 4.1 protocol, allowing standard POSIX operations like reading, writing, renaming, and directory creation without altering existing code or moving data out of S3.
