AWS has released an updated Amazon Bedrock AgentCore runtime with sessions supporting up to 8 vCPUs and 32 GB of memory, four times the previous capacity. AWS says sessions start in under 2 seconds and support container images up to 10 GB.

The runtime reclaims released memory within minutes and scales idle agents to zero. Each session retains its own hardware-isolated virtual machine, identity, policy and audit trail. Agents can also mount filesystems such as Amazon S3 buckets through FUSE support.

The release is available across North America, South America, Europe and Asia Pacific. Binding each session to its own storage folder through session-labeled credentials is scheduled for re:Invent.
