+
+This guide will show you how you can share portable resources between Radius applications.
+
+## Pre-requisites
+
+- [rad CLI]({{< ref "/guides/tooling/rad-cli/overview" >}})
+- [rad development environment]({{< red "getting-started" >}})
+
+## Step 1: Define an environment-scoped resource
+
+Portable resources can be environment-scoped, where they follow the lifecycle of an environment instead of an application. Define a resource, such as a Redis cache, in your app.bicep file:
+
+{{< rad file="snippets/app.bicep" embed=true >}}
+
+## Step 2: Deploy resource
+
+Deploy the resource with [`rad deploy`]({{< ref rad_deploy >}}), using the 'local-dev' Recipe:
+
+```bash
+rad deploy app.bicep
+```
+
+You should see the resource deployed into your environment:
+
+```Building .\app.bicep...
+Deploying template '.\app.bicep' into environment 'default' from workspace 'default'...
+
+Deployment In Progress...
+
+...                  shared-cache    Applications.Datastores/redisCaches
+
+Deployment Complete
+
+Resources:
+    shared-cache    Applications.Datastores/redisCaches
+```
+
+## Step 3: Verify the resource was deployed
+
+Run [`rad resource show`]({{< ref rad_resource_show >}}) to verify the resource was deployed into the environment's Kubernetes namespace:
+
+```bash
+rad resource show rediscaches shared-cache -o json
+```
+
+You should see the raw JSON output, including the `outputResources` property which shows the Kubernetes namespace the Redis cache was deployed into. It will match the environment's namespace ('default') and not an application's ('default-app1', 'default-app2'):
+
+```
+{
+  "id": "/planes/radius/local/resourcegroups/default/providers/Applications.Datastores/redisCaches/shared-cache",
+  "location": "global",
+  "name": "shared-cache",
+  "properties": {
+    "application": "",
+    "environment": "/planes/radius/local/resourceGroups/default/providers/applications.core/environments/default",
+    "host": "redis-bvempevrr4ygm.default.svc.cluster.local",
+    "port": 6379,
+    "provisioningState": "Succeeded",
+    "recipe": {
+      "name": "default"
+    },
+    "resourceProvisioning": "recipe",
+    "status": {
+      "outputResources": [
+        {
+          "id": "/planes/kubernetes/local/namespaces/default/providers/core/Service/redis-bvempevrr4ygm",
+          "radiusManaged": true
+        },
+        {
+          "id": "/planes/kubernetes/local/namespaces/default/providers/apps/Deployment/redis-bvempevrr4ygm",
+          "radiusManaged": true
+        }
+      ]
+    },
+    "tls": false,
+    "username": ""
+  },
+  "systemData": {},
+  "tags": {},
+  "type": "Applications.Datastores/redisCaches"
+}
+```
+
+## Done
+
+Now that you have an environment-scoped resource you can define connections to it from any Radius container from any application. You can also cleanup with the resource with [`rad resource delete`]({{< ref rad_resource_delete >}}):
+
+```bash
+rad resource delete rediscaches shared-cache -y
+```
