Amazon Bedrock AgentCore runtime upgrade
The story so far
Amazon has launched an upgraded AgentCore runtime, providing a secure environment for each session through hardware-isolated Firecracker micro-virtual machines. The new version boosts startup speed by 15x, extends computing by 4x, and improves efficiency by 68%, supporting up to 8 vCPUs and 32 GB memory, along with 10 GB container images, with session startup times under 2 seconds. Each session still runs in its own hardware-isolated environment, with independent identity, access policies, and audit trails. The new version no longer requires warm pools and pre-configured clusters to manage cold starts, reducing memory consumption per session by up to 68% for multi-round agents with natural pauses. For always-on agents, baseline pricing is committed per session with memory baseline, billed at the lowest fee, and can burst up to four times the baseline as needed.

- AWS Machine Learning BlogAmazon Bedrock AgentCore runtime V2 architecture mode: Accelerating session startup
Amazon Bedrock AgentCore runtime V2 reduces session startup time to about 2 seconds by preparing the environment once and using a snapshot for recovery, while also reclaiming unused memory. V2 supports building hooks to load large files or CLI, suitable for scenarios requiring resource preparation in advance. Session startup time can be measured via CloudWatch metrics, prioritizing optimization of platform overhead or code execution time.
