The new AgentCore runtime: Elastic, optimized, and consistently fast starts
AWS launches new AgentCore runtime with elastic memory reclamation and consistent cold starts for production agents.
“Agents are no longer experiments.”
AWS announced a new version of Amazon Bedrock AgentCore runtime, a managed serverless compute layer for deploying agents, adding per-session memory reclamation, consistent cold-start times regardless of container size or concurrency, and usage-based billing. It matters because it targets the shift from short chatbot sessions to long-running, ambient, always-on production agents, reflecting how the industry is hardening infrastructure for autonomous agent workloads at scale.
