Briefing

Assuming the goal is to build a highly scalable, robust, reliable checkout service that meets the standards of AWS Well-Architected, this project takes the most of the serverless design pattern and communicate with other microservices through Amazon SNS.

Architecture

• Checkout Microservice
  • It starts the checkout process by doing what the application needs and then communicate via SNS to the invoice microservice.
• Invoice Microservice
  • Generate its invoice file, uploads to S3 and communicate via SNS to both logger and notification microservices.
• Logger Microservice
  • Receive the information, customer details, generated invoice S3 URL and then persists on DynamoDB.
• Notification Microservice
  • When the invoice microservice informs that the invoice itself was successfully generated, then this microservice sends the notification to the customer.

Dependencies

• Node.js
• Serverless
• AWS Account

Setup

• Copy secrets.json.example, update with your information and rename it to secrets.json.
• Run $ serverless config credentials -o --provider aws --key=YOUR_AWS_KEY --secret YOUR_AWS_SECRET.
