E-Commerce Platform on AWS

Note: There is a story behind this Project. You'd want to read through it to get a sense of how I reached the conclusions for some technical decisions. Also, it gives you a better perspecitve on my thought process as I worked on it. Have a read on my dev.to page. I'd love to hear your thoughts on it as you follow through this series.

Architecture Overview

Figure 1: High-level architecture of the e-commerce platform on AWS

Core Architecture Components

Frontend Services

• Amazon S3: Hosts static website content (HTML/CSS/JS)
• Amazon CloudFront: Global CDN for low-latency content delivery
• AWS WAF: Web application firewall for security protection
• Certificate Manager: Provides SSL/TLS certificates for secure HTTPS connections

Backend Services

• Amazon API Gateway: REST API endpoint management
• Application Load Balancer: Distributes traffic across backend services
• Amazon Cognito: User authentication and authorization

Data & Integration Layer

• AWS Secrets Manager: Secure storage of credentials and secrets
• Parameter Store: Centralized configuration management
• Amazon ElastiCache (Redis): Caching layer for improved performance
• Amazon SNS: Notification service for event-driven architecture

Payment Processing

• Stripe Integration:
  • Direct Stripe API connections
  • Stripe callback handlers for payment verification

Key Features

1. Secure Architecture:

   • End-to-end encryption (SSL/TLS)
   • WAF protection against common web exploits
   • Cognito for secure user management

2. Scalable Infrastructure:

   • CloudFront CDN for global availability
   • Load balanced backend services
   • Redis caching for high throughput

3. Payment Processing:

   • PCI-compliant Stripe integration
   • Asynchronous payment verification via callbacks

Deployment Notes

• All AWS resources provisioned through Infrastructure as Code (Terraform)
• Environment variables managed through Parameter Store
• Secrets (API keys, DB credentials) secured via Secrets Manager
