Microservices-based E-Commerce Application

---

Overview

This project is a microservices-based e-commerce platform designed for scalability, modularity, and security. It leverages Apollo Federated GraphQL for a unified API layer and is deployed on AWS using scalable and resilient cloud services.

---

Key Components

1. Federated Gateway with Apollo GraphQL

• Federated Gateway: Combines GraphQL schemas from all microservices into a unified API.
• Advantages:
  • Enables independent service development and scalability.
  • Simplifies API management with schema stitching.
  • Reduces client-side integration complexity.

---

2. CICD Pipeline

The CI/CD pipeline automates application delivery using AWS:

• CodeCommit: Version control for source code.
• CodeBuild: Builds and packages deployable artifacts.
• CodePipeline: Manages build, test, and deployment workflows.
• CodeDeploy: Automates container deployments to Amazon ECS.

---

3. Microservices Deployment

Each service is deployed as a containerized task using Amazon ECS Fargate, enabling:

• Independent scaling.
• Fault isolation.
• Efficient resource management.

Services include:

• UserService, SellerService, OrderService, ProductService, etc.

---

4. Secure Networking

• Public Subnet: Hosts Load Balancers and resources requiring internet access.
• Private Subnet: Secures backend services and database resources.

Traffic to the private subnet is routed through the Load Balancer for enhanced security.

---

5. Persistent Storage

• Amazon S3: Stores static assets such as product images.
• Amazon DynamoDB: Handles high-speed NoSQL data.
• Amazon RDS: Manages relational data for transactions.
• Amazon ElastiCache: Caches frequent queries for faster responses.

---

6. Monitoring and Notifications

• Amazon CloudWatch: Tracks metrics and logs for system performance.
• AWS SNS: Sends notifications for events and alerts.
• AWS SES: Handles email-based communication.

---

Key Features

• Federated GraphQL Gateway: A centralized API layer connecting all microservices.
• CI/CD Automation: Simplified deployment with AWS CodePipeline and CodeDeploy.
• Containerized Microservices: Serverless scalability with Amazon ECS Fargate.
• Resilient Messaging: Asynchronous communication via Amazon MQ.
• Global Content Delivery: Low-latency distribution with Amazon CloudFront.

---

Getting Started

1. Clone the repository using AWS CodeCommit.
2. Trigger the build pipeline with AWS CodePipeline.
3. Deploy the application to Amazon ECS via CodeDeploy.
4. Access the application using the public Load Balancer endpoint.
