AWS updates Amazon Bedrock AgentCore runtime for faster, more secure AI agent sessions

AWS said the latest Amazon Bedrock AgentCore runtime is available today across regions in North America, South America, Europe and Asia Pacific. The managed compute layer keeps each session inside its own hardware-isolated Firecracker MicroVM with separate identity, policy and audit trail. The update adds restored initialized environments, reclaimed unused memory, and support for mounting and saving work to filesystems such as Amazon S3 with FUSE support. AWS also said per-session storage scoping will arrive by re:Invent.
