# Creating an ECS Service

This section of the tutorial shows you how to deploy a web application with [AWS Elastic Container Service (ECS)](https://aws.amazon.com/ecs/).

For a full discussion of the benefits of using EKS vs. ECS, consult[ this AWS blog](https://aws.amazon.com/blogs/containers/amazon-ecs-vs-amazon-eks-making-sense-of-aws-container-services/).

{% hint style="info" %}
Instead of creating a DuploCloud Service with AWS ECS, you can alternatively finish the tutorial by:

* [Creating an AWS EKS Service in DuploCloud](https://docs.duplocloud.com/docs/automation-platform/overview/quick-start/quick-start-eks-services) running Docker containers or
* [Creating a DuploCloud native Docker Service](https://docs.duplocloud.com/docs/automation-platform/overview/quick-start/quick-start-duplocloud-docker-services).
  {% endhint %}

## Deploying an AWS ECS Service in DuploCloud

Unlike AWS EKS, creating and deploying services and apps with ECS requires creating a [Task Definition](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definitions.html), a blueprint for your application. Once you create a Task Definition, you can run it as a Task or as a Service. In this tutorial, we run the Task Definition as a Service.

To deploy your app with AWS ECS in this ECS tutorial, you:

1. Create a **Task Definition** using ECS.
2. Create a DuploCloud Service named **webapp**, backed by a Docker image.
3. Expose the app to the web with a **Load Balancer**.
4. Complete the tutorial by testing your application.

*Estimated time to complete remaining tutorial steps: 30-40 minutes*

## Network Architecture and Configurations

Behind the scenes, the topology that DuploCloud creates resembles this low-level configuration in AWS.
