Google's Agent Substrate hits 1.0 and GA on GKE, donated to CNCF with gVisor
Announced Nov 5 for KubeCon NA, the open-source Kubernetes runtime snapshots idle agents to storage and restores them onto a warm worker in under 500 ms, which Google says gives about 10x container density. Agent Substrate, gVisor, and OpenRL join the CNCF Sandbox, and the GKE version needs a Standard cluster on 1.37 or later (no Autopilot).
