Amazon Bedrock AgentCore Runtime now supports bring-your-own file system from Amazon S3 Files and Amazon EFS
Amazon Web Services announced that its Bedrock AgentCore Runtime now supports bring-your-own file system functionality, allowing developers to directly attach Amazon S3 Files and Amazon EFS access points to AI agent runtimes. The new capability mounts file systems into agent sessions at developer-specified paths, enabling agents to perform standard file operations without requiring custom mount code, privileged containers, or pre-session download orchestration. The feature addresses persistent data access challenges for AI agents by supporting shared resources like skills libraries, tool collections, reference datasets, and knowledge bases that need to persist across sessions and microVM lifecycles. Developers can choose between Amazon S3 Files for dual API access with automatic synchronization or Amazon EFS access points for dedicated NFS file systems, both delivering sub-millisecond latency and NFS close-to-open consistency. This enables new architectural patterns including shared skill loading, workflow persistence across sessions, and multi-agent collaboration on common datasets.
Why It Matters
This enhancement addresses a critical limitation in AI agent deployment by solving data persistence and sharing challenges that have made enterprise AI workflows difficult to implement. The ability to maintain state and share resources across agent sessions without performance penalties opens new possibilities for complex, multi-step AI automation and collaborative agent architectures in enterprise environments.
