Retail Demo Store

A sample retail web application and workshop platform intended as an educational tool for demonstrating how AWS infrastructure and services can be used to build compelling customer experiences for eCommerce, retail, and digital marketing use-cases.

This project is intended for educational purposes only and not for production use.

The Retail Demo Store is an eCommerce reference implementation designed to showcase how AWS services can be used to build compelling shopping experiences using modern architecture and design patterns.

At the heart of the Retail Demo Store is a collection of polyglot microservices hosted in Amazon Elastic Container Service (AWS Fargate) that represent domain constructs such as products, carts, orders, and users as well as services for search and recommendations. While the web user interface is served by Amazon CloudFront and Amazon S3.

The architecture is supported by several managed services including Amazon Cognito, Amazon Pinpoint, Amazon Personalize, and Amazon OpenSearch Service (successor to Amazon Elasticsearch Service). The web user interface is built using the Vue.js framework with AWS Amplify to provide integrations with Cognito for registration/authentication and event streaming to Pinpoint and Personalize (Event Tracker). Finally, AWS CodePipeline is leveraged to demonstrate how AWS development services can be used to orchestrate the build and deployment process with the Retail Demo Store.

Hands-On Workshops

This project is designed to provide you with an environment in which you can learn to use AWS services to modify the behavior of an ecommerce application, based on business requirements. This can be done in a group setting or as an individual using self-paced workbooks. Currently there are workshops for adding search, personalization, experimentation frameworks, a/b testing, analytics, customer data platforms (CDPs), messaging, and more.

In order to use the workshops, you will need to deploy the Retail Demo Store into an AWS account, using one of the methods described in the Getting Started or Developers sections below. This is necessary because the workshops run in SageMaker Jupyter notebooks, which provide an interactive Python environment where you can execute code in the Retail Demo Store environment.

AWS Service	Workshops Overview	Workshop Links	Level	Duration
Amazon Personalize	The Retail Demo Store uses Amazon Personalize to provide similar item recommendations, search re-ranking based on user preferences, and product recommendations based on user item interactions.

Supported Regions

The Retail Demo Store has been tested in the AWS regions indicated in the deployment instructions below. Additional regions may be supported depending on service availability and having the Retail Demo Store's deployment resources staged to an S3 bucket in the targeted region.

Getting Started

IMPORTANT NOTE: Deploying this demo application in your AWS account will create and consume AWS resources, which will cost money. In addition, some features such as account registration via Amazon Cognito and the messaging workshop for Amazon Pinpoint require users to provide a valid email address and optionally a phone number to demonstrate completely. Therefore, to avoid ongoing charges and to clean up all data, be sure to follow all workshop clean up instructions and shutdown/remove all resources by deleting the CloudFormation stack once you are finished.

The Retail Demo Store experience is for demonstration purposes only. You must comply with all applicable laws and regulations, including any laws and regulations related to email or text marketing, in any applicable country or region.

If you are a developer looking to contribute to the Retail Demo Store, please see the Developer section below.

To get the Retail Demo Store running in your own AWS account, follow these instructions. If you are attending an AWS-led event where temporary AWS accounts are provided, this has likely already been done for you. Check with your event administrators.

Step 1 - Get an AWS Account

If you do not have an AWS account, please see How do I create and activate a new Amazon Web Services account?

Step 2 - Log into the AWS Console

Log into the AWS console if you are not already.

Note: If you are logged in as an IAM user, ensure your account has permissions to create and manage the necessary resources and components for this application.

Step 3 - Deploy to your AWS Account

The following CloudFormation launch options will set the deployment approach to "CodeCommit". You can ignore the GitHub related template parameters. After clicking one of the Launch Stack buttons below, follow the procedures to launch the template. Be sure to enter a CloudFront stack name in lowercase letters (numbers and hyphens are okay too).

With this deployment option, the CloudFormation template will import the Retail Demo Store source code into a CodeCommit repository in your account and setup CodePipeline to build and deploy into ECS from that respository.

Region name	Region code	Launch
US East (N. Virginia)	us-east-1
US West (Oregon)	us-west-2
Europe (Ireland)	eu-west-1
Asia Pacific (Tokyo)	ap-northeast-1
Asia Pacific (Sydney)	ap-southeast-2

The CloudFormation deployment will take approximately 40 minutes to complete.

Notes:

Amazon Personalize Campaigns

If you chose to have the Amazon Personalize campaigns automatically built post-deployment, this process will take an additional 2-2.5 hours. This process happens in the background so you don't have to wait for it to complete before exploring the Retail Demo Store application and architecture. Once the Personalize campaigns are created, they will be automatically activated in the Web UI and Recommendations service. You can monitor the progress in CloudWatch under the /aws/lambda/RetailDemoStorePersonalizePreCreateCampaigns log group.

Amazon Pinpoint Campaigns

If you chose to have the Amazon Pinpoint campaigns automatically built (‘Auto-Configure Pinpoint’ is set to ‘Yes’ in the CloudFormation template), this process will take an additional 20-30 minutes. Once the Pinpoint campaigns are created, they will be automatically visbile in the Web UI. However, there are some manual steps described below that are required for enabling the Pinpoint channels.

Pinpoint Emails:

PinpointEmailFromAddress: By Default, AWS Accounts have emails set up in a sandbox environement. To enable the functionality, you need to complete either of the following manual steps.

Verifying the email addresses you want to send and receive emails from. More info here. This is the easiest and recommended approach for demos and workshops.
Request to be removed from the sandbox environment. More info here. This is recommended only for production workloads and the Retail Demo Store is intended to be used for demonstration purposes only.

Pinpoint SMS

PinpointSMSLongCode: A dedicated long code (i.e. a phone number) obtained for Amazon Pinpoint to send and receive messages at. You also need to enable two way SMS for this long code using Pinpoint. Follow steps 2 and 3 in the Enable Pinpoint SMS Channel & Obtain Dedicated Long Code section of the Pinpoint workshop to get a long code and enable two way SMS for it. When deploying Retail Demo Store, enter the number as a parameter. The number should be formatted along with the country code and without any spaces or brackets. For Example: enter “+1XXXXXXXXXX” for a long code based in the United States.

Step 4 - Using the Retail Demo Store Web Application

Once you launch the CloudFormation stack, all of the services will go through a build and deployment cycle and deploy the Retail Demo Store.

Compiling and deploying the web UI application and the services it uses can take some time. You can monitor progress in CodePipeline. Until this completes, you may see a Sample Application when accessing the public WebUI URL.

You can find the URL for the Retail Demo Store Web UI in the Outputs of your main CloudFormation stack (called retaildemostore unless you changed that option in the steps above).

Look for the "WebURL" output parameter.

Accessing Workshops

The Retail Demo Store environment is designed to provide a series of interactive workshops that progressively add functionality to the Retail Demo Store application.

The workshops are deployed in a SageMaker Jupyter environment that is deployed in your CloudFormation stack. To access the Retail Demo Store workshops after the CloudFormation stack has completed, browse to Amazon SageMaker in your AWS console, and then select "Notebook > Notebook instances" in SageMaker.

You will see a running Notebook instance. Click "Open JupyterLab" for the Retail Demo Store notebook instance.

Here you will find several workshops in a directory structure in the notebook instance. See the workshops page for details.

Developer Instructions

If you're interested in contributing enhancements, features, or fixes to the Retail Demo Store, please see the Developer Instructions for details on how to setup your local environment and deployment environment.

Delivering a Demo of the Retail Demo Store

Once you have deployed the Retail Demo Store, you may want to walk through the demonstration guide to learn how to show the features the Retail Demo Store provides.

The intent of the Retail Demo Store is to 1) provide a tool to demonstrate the capabilities of key AWS services for retail, eCommerce, and digital marketing use-cases and 2) provide a platform for individual AWS customers to step through workshops and AWS internal teams to deliver customer-facing workshops, Immersion Days, hackathons, and similar types of events.

Known Issues/Limitations

The application was written for demonstration and education purposes and not for production use.
You currently cannot deploy this project multiple times in the same AWS account and the same AWS region. However, you can deploy the project into separate supported regions within the same AWS account.
Make sure your CloudFormation stack name uses all lowercase letters.
Currently only tested in the AWS regions provided in the deployment instructions above. The only limitation for deploying into other regions is availability of all required services.
- Amazon IVS is currently only supported in the N. Virginia (us-east-1), Oregon (us-west-2), and Ireland (eu-west-1) regions. Therefore, to deploy the Retail Demo Store in a region that does not support IVS, be sure to select to use the Default IVS Streams CloudFormation template parameter.

Troubleshooting / FAQs

Q: When accessing the Retail Demo Store web application after deploying the project, a CloudFront error is displayed. What's wrong?

A: Sign in to the AWS account/region where the project was deployed and browse to CodePipeline. Verify that the pipeline with "WebUIPipeline" in the name has successfully been built. If it failed, inspect the details of the Build stage to diagnose the root cause.

Q: When accessing the Retail Demo Store web application after deploying the project, the home page shows spinning icons and products are never loaded. What's wrong?

A: The most likely cause is an error building or deploying one or more of the microservices. Sign in to the AWS account/region where the project was deployed and browse to CodePipeline. Verify that all of the Retail Demo Store pipelines have completed successfully. Inspect the details for any that have failed to determine the root cause. Sometimes just manually triggering a build/deploy will resolve the issue.

Q: This project is expensive to run (or keep running). How can I reduce the running cost of a deployment?

A: The most costly service in the project for an idle deployment is Amazon Personalize. You can eliminate Personalize idle costs by stopping all Amazon Personalize recommenders and deleting all campaigns in the Retail Demo Store dataset group for Personalize. This just shuts down the real-time inference endpoints; the datasets and ML models will remain. You should also change all of the recommender and campaign ARN parameter values in the AWS Systems Manager Parameter Store to NONE, leaving the parameter values for filters and the event tracker alone. These parameter names start with /retaildemostore/personalize/ (e.g., /retaildemostore/personalize/recommended-for-you-arn). Once you complete these steps, the storefront will fall back to default behavior for recommending products from the catalog. To reactive Personalize, start the recommenders and create campaigns and then set the recommender and/or campaign ARNs back in the Systems Manager Parameter Store. The storefront will automatically start showing recommendations from Personalize again.
