terra-serverless

This is a terraform project that automates the deployment of a proof of concept for a serverless solution on AWS.

Architecture

The architecture involved sending customer order details to an API Gateway. The API Gateway is integrated with an SQS queue that stores the details and triggers a lambda function to process the order. The Lambda function processes the order, extracts important order details and stores them in a DynamoDB table. This DynamoDB table has DynamoDB streams enabled which captures all "PUTItem" requests and transmits to a second Lambda function. This second Lambda function will then refine the purchase details and sends to a logistics team via SNS notifications.

How to Use

• Clone the repository
• cd into the repository root directory
• Run terraform init command
• Run terraform plan to view the expected infrstructure changes
• Run terraform apply to deploy the infrastructure.

Test

To test this out:

• Go to the API gateway console, click on the POC-API
• Click on the POST method.
• Add the following into the Request body: { "item": "latex gloves", "customerID":"12345"}
• You should get a HTTP 200 response
• Also you hshould receive an email notification.

Destroy

• To tear down the infrastructure, run terraform destroy.
