GKE introduces Agent Substrate to scale agentic workloads efficiently
Google Kubernetes Engine (GKE) now offers Feature Agent Substrate, designed to run agentic workloads at scale on GKE clusters. This new capability efficiently manages resources by suspending idle agents and taking snapshots of their active memory and local files. When an agent is triggered, its state is restored onto an available sandbox with sub-second latency, bypassing standard Kubernetes control plane bottlenecks to support more concurrent agents per machine. Agent Substrate is available for evaluation and non-production use, with production support offered through a limited GA allowlist program.

Agent Substrate on GKE is now available for evaluation and non-production use. Production support is offered on an allowlist basis under a limited GA program. Agent Substrate runs agentic workloads at scale on GKE clusters. To reduce resource usage, Agent Substrate suspends idle agents and takes a snapshot of the agent's active memory (RAM) and local files. When a suspended agent is triggered, the system restores the agent's state onto an available sandbox with sub-second latency. Agent Substrate improves on the capabilities of Agent Sandbox by bypassing the bottlenecks of the standard Kuberne
