Google Cloud launches open-source Agent Substrate runtime on GKE with production support
Summary
Google Cloud launches the open-source Agent Substrate runtime on Google Kubernetes Engine, offering allowlisted production support and isolating untrusted AI agent code in Cloud Hypervisor microVMs or gVisor sandboxes while resuming idle agents in under 500ms.
Key Points
- Google Cloud launches the open-source Agent Substrate runtime on GKE, with production GA support available through an allowlist.
- Agent Substrate uses Cloud Hypervisor microVMs or gVisor sandboxes and an integrated gateway to isolate untrusted agent code and enforce network policies.
- The runtime suspends idle agents, packs more than 1,000 dormant agents per host, and resumes sandboxes in under 500ms.
