Product and Coupon Microservices for Discount Management

(Deployed on AWS, Also Available on Docker)

Overview

Get discounts on products by using coupon codes. I've built two microservices that work together to make this happen: a product microservice and a coupon microservice.

This project consists of two microservices and a MySQL database. The microservices are deployed on AWS Elastic Beanstalk while the database is hosted on Amazon RDS.

Microservices

Microservice 1: Coupon Microservice

^{repository link} This microservice exposes the following endpoints:

• /coupons - POST: Creates a new coupon (all entries in database should have a unique coupon code)
• /couponsall - GET: Get all available coupons
• /coupons/{code} - GET: Retrieve coupon with given code

Request Examples

• POST /coupons

  {
      "code": "{code}",
      "discount": 30,
      "expDate": "12/12/2024"
  }

Deployment

Coupon microservice is deployed on AWS Elastic Beanstalk at http://Couponmicroservice-env.eba-hsrwim8p.eu-west-1.elasticbeanstalk.com

Microservice 2: Product Microservice

This microservice exposes the following endpoints:

• /products - POST: Creates new product entry and applies any applicable discount based on coupon code provided

Request Examples

• POST /products

  {
      "name":"Corsair VENGEANCE RGB PRO 32GB ",
      "description": "Corsair VENGEANCE RGB PRO 32GB details.",
      "price":100,
      "couponCode": "D15CODE"
  }
