-## Set up service provider
+## Set up connectivity
+
+To ensure that you can connect your Redis Cloud database to the source database hosted an AWS EC2 instance, you need to set up an endpoint service through AWS PrivateLink. To do this:
+
+1. [Create a network load balancer](#create-network-load-balancer) that will route incoming HTTP requests to your database.
+1. [Create an endpoint service](#create-endpoint-service) through AWS PrivateLink.

+    1. Select **Create target group** to [create a target group](https://docs.aws.amazon.com/elasticloadbalancing/latest/application/create-target-group.html) with the following settings:

+            - **Target type**: Select **Instances**.
+            - **Protocol : Port**: Select **TCP**, and then enter the port number where your database is exposed.
+            - The **IP address type** and **VPC** should be selected already and match the VPC you selected earlier.
+        1. In **Register targets**, select the EC2 instance that runs your source database, enter the port, and select **Include as pending below**. Then, select **Create target group** to create your target group. Return **Listeners and routing** in the Network Load Balancer setup.

+    - **Require acceptance for endpoint**: Select **Acceptance required**.
+    - **Supported IP address types**: Select **IPv4**.
+1. Select **Create** to create the endpoint service.
+
+After you create the endpoint service, you need to add Redis Cloud as an Allowed Principal on your [endpoint service VPC permissions](https://docs.aws.amazon.com/vpc/latest/privatelink/configure-endpoint-service.html#add-remove-permissions). 
+
+1. In the Redis Cloud Console, copy the Amazon Resource Name (ARN) provided in the **Setup connectivity** section.
+1. Return to the endpoint service list on the [Amazon VPC console](https://console.aws.amazon.com/vpc/). Select the endpoint service you just created.
+1. Navigate to **Allow principals** tab.
+1. Add the Redis Cloud ARN you copied and choose **Allow principals**.
+1. Save the service name for later.
