For more information see, <a href="/service-mesh/docs/overview">Cloud Service Mesh overview</a>.</span></aside> <p>In a service mesh, your application code doesn't need to know about your networking configuration. Instead, your applications communicate over a data plane, which is configured by a control plane that handles service networking. In this guide, Cloud Service Mesh is your control plane and the Envoy sidecar proxies are your data plane.</p> <p>The Google managed Envoy sidecar injector adds Envoy sidecar proxies to your Google Kubernetes Engine Pods. When the Envoy sidecar injector adds a proxy, it also sets that proxy up to handle application traffic and connect to Cloud Service Mesh for configuration.</p> <p>The guide walks you through a simple setup of Cloud Service Mesh with Google Kubernetes Engine. These steps provide the foundation that you can extend to advanced use cases, such as a service mesh that extends across multiple Google Kubernetes Engine clusters and, potentially, Compute Engine VMs. You can also use these instructions if you are configuring Cloud Service Mesh with Shared VPC.</p> <p>The setup process involves:</p> <ol> <li>Creating a GKE cluster for your workloads.</li> <li>Installing the Envoy sidecar injector and enabling injection.</li> <li>Deploying a sample client and verifying injection.</li> <li>Deploying a Kubernetes service for testing.</li> <li>Configuring Cloud Service Mesh with Cloud Load Balancing components to route traffic to the test service.</li> <li>Verifying the configuration by sending a request from the sample client to the test service.</li> </ol> <figure style="text-align: center"> <a href="/static/service-mesh/docs/images/td-auto-injector.png"> <img src="/static/service-mesh/docs/images/td-auto-injector.png" border="0" Alt="Overview of components deployed as part of this setup guide (click to enlarge)"></a> <figcaption>Overview of components deployed as part of this setup guide (click to enlarge)</figcaption> </figure> <h2 id="prerequisites" data-text="Prerequisites" tabindex="-1">Prerequisites</h2> <p>Before you follow the instructions in this guide, complete the prerequisite tasks described in <a href="/service-mesh/docs/onboarding/prepare-service-routing-envoy-proxyless">Prepare to set up on service routing APIs with Envoy and proxyless workloads</a>.</p> <p>For information about the Envoy version that is supported, see the <a href="/service-mesh/docs/service-routing/release-notes">Cloud Service Mesh release notes</a>.</p> <aside class="note"><strong>Note:</strong><span> The sidecar injector and injected proxy are based on Istio's sidecar injector.
