## Feature Feature GKE ambient networking is now available in[Preview](https://cloud.google.com/products#product-launch-stages) through an allowlist. GKE ambient networking provides a simplified, sidecarless deployment model for a service mesh with Layer 4 capabilities. By moving proxy functionality to node-level components integrated into[GKE Dataplane V2](https://cloud.google.com/kubernetes-engine/docs/concepts/dataplane-v2), ambient networking reduces resource overhead, eliminates workload restarts for proxy updates, and simplifies mesh lifecycle management. The Preview release supports single-cluster Layer 4 mesh capabilities using the[Gateway API](https://cloud.google.com/kubernetes-engine/docs/concepts/gateway-api), which includes mutual TLS (mTLS), service discovery, Layer 4 traffic management, and Layer 4 telemetry.
