Amazon introduced S3 Files, a shared file system built atop Amazon S3 that offers low-latency, full file system semantics without data duplication or migration. Using Amazon EFS architecture, it translates file operations into optimized S3 requests, allowing file-based applications and AI agents to work directly with S3 objects transparently.
This innovation removes the need for separate file storage systems, enabling thousands of compute resources simultaneous access with strong durability and cost-effectiveness. It supports existing S3 data, providing caching and multiple terabytes per second aggregate read throughput. S3 Files facilitates workflows in analytics, machine learning, and software agents with familiar tools and no code changes.
