+## Overview
+
+This example shows how we can route between gRPC clients and servers using App Mesh.
+
+![System Diagram](./howto-grpc.png "System Diagram")
+
+### Color Server
+
+The Color Server is a gRPC server that implements [color.ColorService](./color.proto). Additionally, it implements the [gRPC Health Checking Protocol](https://github.com/grpc/grpc/blob/master/doc/health-checking.md) which we will configure App Mesh to use as the health check for the its virtual-nodes.
+
+### Color Client
+
+The Color Client is a HTTP/1.1 front-end webserver that maintains a persistent gRPC connection to the Color Server. The HTTP/1.1 webserver will be connected to an internet-facing ALB. It forwards requests to `/getColor` and `/setColor` to the same methods in [color.ColorService](./color.proto). Initially, the Envoy sidecar for the Color Client will be configured to only route the `GetColor` gRPC method, but we will update the route to forward all methods to the Color Server.
+
+## Setup
+
+1. This example uses features in the [App Mesh Preview Channel](https://docs.aws.amazon.com/app-mesh/latest/userguide/preview.html). You'll need to install the latest `appmesh-preview` model to deploy it
+    ```
+    aws configure add-model \
+        --service-name appmesh-preview \
+        --service-model https://raw.githubusercontent.com/aws/aws-app-mesh-roadmap/master/appmesh-preview/service-model.json
+    ```
+2. Clone this repository and navigate to the walkthrough/howto-grpc folder, all commands will be ran from this location
+3. **Project Name** used to isolate resources created in this demo from other's in your account. e.g. howto-grpc
+    ```
+    export PROJECT_NAME=howto-grpc
+    ```
+4. **Your** account id:
+    ```
+    export AWS_ACCOUNT_ID=<your_account_id>
+    ```
+5. **Region** e.g. us-west-2
+    ```
+    export AWS_DEFAULT_REGION=us-west-2
+    ```
+6. **ENVOY_IMAGE** environment variable is not set to App Mesh Envoy, see https://docs.aws.amazon.com/app-mesh/latest/userguide/envoy.html
+    ```
+    export ENVOY_IMAGE=...
+    ```
+7. Setup using cloudformation
+    ```
+    ./deploy.sh
+    ```
+   Note that the example apps use go modules. If you have trouble accessing https://proxy.golang.org during the deployment you can override the GOPROXY by setting `GO_PROXY=direct`
+   ```
+   GO_PROXY=direct ./deploy.sh
+   ```
+
+## Verification
+
+1. After a few minutes, the applications should be deployed and you will see an output such as:
+    ```
+    Successfully created/updated stack - howto-grpc-app
+    Public endpoint:
+    http://howto-Publi-5555555.us-west-2.elb.amazonaws.com
+    ```
+   This is the public endpoint to access the Color Client APIs. Export it.
+    ```
+    export COLOR_ENDPOINT=<your_public_endpoint>
+    ```
+2. Try curling the `/getColor` API
+    ```
+    curl $COLOR_ENDPOINT/getColor
+    ```
+   You should see `no_color`. The color returned by the Color Service via the Color Client can be configured using the `/setColor` API.
+3. Attempt to change the color by curling the `/setColor` API
+    ```
+    curl -i -X POST -d "blue" $COLOR_ENDPOINT/setColor
+    ```
+   We passed the `-i` flag to see any error information in the response. You should see something like:
+    ```
+    HTTP/1.1 404 Not Found
+    Date: Fri, 27 Sep 2019 01:27:42 GMT
+    Content-Type: text/plain; charset=utf-8
+    Content-Length: 40
+    Connection: keep-alive
+    x-content-type-options: nosniff
+    x-envoy-upstream-service-time: 1
+    server: envoy
+
+    rpc error: code = Unimplemented desc = 
+    ```
+   This is because our current mesh is only configured to route the gRPC Method `GetColor`:
+   
+   (from [mesh/route.json](./mesh/route.json))
+    ```json
+    {
+      "grpcRoute": {
+        "action": {
+          "weightedTargets": [
+            {
+              "virtualNode": "color_server",
+              "weight": 100
+            }
+          ]
+        },
+        "match": {
+          "serviceName": "color.ColorService",
+          "methodName": "GetColor"
+        }
+      }
+    }
+    ```
+   We'll remove the `methodName` match condition in the gRPC route to match all methods for `color.ColorService`.
+4. Update the route to [mesh/route-all-methods.json](./mesh/route-all-methods.json):
+    ```
+    aws appmesh-preview update-route --mesh-name $PROJECT_NAME-mesh --virtual-router-name virtual-router --route-name route --cli-input-json file://mesh/route-all-methods.json
+    ```
+5. Now try updating the color again
+    ```
+    curl -i -X POST -d "blue" $COLOR_ENDPOINT/setColor
+    ```
+   You'll see that we got a `HTTP/1.1 200 OK` response. You'll also see `no_color` in the response. But this is the previous color being returned after a successful color update.
+6. You can verify that the color did, in fact, update
+    ```
+    curl $COLOR_ENDPOINT/getColor
+    ```
+
+### Teardown
+When you are done with the example you can delete everything we created by running:
+```
+./deploy.sh delete
+```
