Google has made Agent Substrate available on Google Kubernetes Engine. The open-source runtime is designed to run millions of sandboxes at 10x the density of standard container runtimes, with sub-500ms resume operations and more than 500 suspend/resume activations per second. It includes zero-trust kernel and network isolation and runs on any Kubernetes infrastructure. Those details make the release relevant to teams evaluating the operational requirements of large-scale agent ex*****on.
