Exploring the AWS Serverless Application Repository: A Hands-On Guide

The AWS Serverless Application Repository (SAR) is a valuable resource for developers looking to quickly deploy serverless applications and components without having to write extensive code from scratch. It enables you to discover, configure, and deploy serverless applications and resources with ease. In this blog, we will dive into the AWS Serverless Application Repository, explore its benefits, and walk through a hands-on example to help you get started.

What is the AWS Serverless Application Repository?

The AWS Serverless Application Repository is a managed repository for serverless applications. These applications are built using AWS Lambda and can include a variety of other AWS services like API Gateway, DynamoDB, and more. SAR allows you to:

  • Discover pre-built serverless applications and components.

  • Share your own applications with the community.

  • Quickly deploy and manage serverless applications with minimal configuration.

Benefits of the AWS Serverless Application Repository

  1. Speed and Efficiency: Deploy applications quickly without having to build from scratch.

  2. Community-Driven: Leverage applications and components shared by other developers.

  3. Scalability: Easily scale your applications as needed.

  4. Cost-Effective: Pay only for the resources you use, with no upfront costs.

  5. Security: Utilize applications that follow AWS's security best practices.

Hands-On Example: Deploying a Serverless URL Shortener

In this hands-on example, we will deploy a serverless URL shortener application from the AWS Serverless Application Repository.


  • An AWS account.

  • AWS CLI installed and configured.

  • Basic knowledge of AWS Lambda and serverless architecture.

Step 1: Access the AWS Serverless Application Repository

  1. Log in to the AWS Management Console.

  2. Navigate to the AWS Serverless Application Repository by searching for it in the AWS services menu.

Step 2: Find the URL Shortener Application

  1. In the AWS Serverless Application Repository, search for "URL Shortener."

  2. Select a URL shortener application that fits your needs. For this example, we will use the "serverless-url-shortener" by AWS.

Step 3: Deploy the Application

  1. Click on the application to view its details.

  2. Click the "Deploy" button.

  3. You will be prompted to configure the application parameters. Enter a unique name for your deployment stack and configure any additional parameters as required.

  4. Click "Deploy."

Step 4: Monitor the Deployment

  1. Navigate to the AWS CloudFormation console to monitor the progress of your stack deployment.

  2. Once the stack is successfully deployed, you will see a list of resources created by the application.

Step 5: Test the URL Shortener

  1. After deployment, navigate to the API Gateway endpoint created by the application.

  2. Use the endpoint to shorten URLs by making HTTP POST requests with the URL you want to shorten.

  3. The response will include a shortened URL which you can use to redirect to the original URL.

Example: Using the URL Shortener

curl -X POST -H "Content-Type: application/json" -d '{"url": "https://www.example.com"}' https://your-api-gateway-endpoint/shorten

This command will return a shortened URL that you can use to access "https://www.example.com."


The AWS Serverless Application Repository is a powerful tool for accelerating the development and deployment of serverless applications. By leveraging pre-built applications like the URL shortener, you can save time and focus on building unique features for your projects.
