News

This article announces managed session storage for Amazon Bedrock AgentCore Runtime in public preview, enabling agents to persist filesystem state across stop and resume cycles.

  • Agents can now persist files, packages, and artifacts across session stops
  • Automatic data replication to durable storage with no code changes required
  • Up to 1 GB storage per session, retained for 14 days of idle time
  • Supports standard Linux filesystem operations including files, directories, symlinks
