# ECS Services and Load Balancers

## Prerequisites

Before you create an ECS Service and Load Balancer, you must create a [Task Definition](https://docs.duplocloud.com/docs/automation-platform/overview/aws-services/containers/ecs-containers-and-task-definitions) to run the Service. You can define multiple containers in your Task Definition.

## Adding an ECS Service and Load Balancer Listener

{% hint style="info" %}
For an end-to-end example of deploying an application using an ECS Service, see the [AWS Quick Start Tutorial](https://docs.duplocloud.com/docs/automation-platform/overview/quick-start) and choose the [Creating an ECS Service](https://docs.duplocloud.com/docs/automation-platform/overview/quick-start/quick-start-ecs-services) option.
{% endhint %}

Tasks run until an error occurs or a user terminates the Task in the ECS Cluster.

1. Navigate to **Cloud Services** -> **ECS**.
2. In the **Task Definitions** tab, select the Task Definition Family Name. This is the [Task Definition **Name** that you created ](https://docs.duplocloud.com/docs/automation-platform/overview/aws-services/containers/ecs-containers-and-task-definitions)prepended by a unique DuploCloud identifier.
3. In the **Service Details** tab, click the **Configure ECS Service** link. The **Add ECS Service** page displays.
