— A Practical Deep Dive into Cloud-Native Architecture

E-commerce is no longer a luxury — it's a necessity. Whether you're building a niche D2C brand or launching a marketplace like Amazon, scalability, availability, and security are critical. That's where AWS shines.
In this blog, we walk you through how to build an end-to-end e-commerce platform using Amazon Web Services, with real-world architecture and tools used by industry giants.

Architecture Overview
We break down our e-commerce platform into the following core components:

Frontend (UI/UX):

• Hosted on Amazon S3 with CloudFront CDN
• Built with React or Angular

Backend Services:

• REST APIs using AWS Lambda + API Gateway (Serverless)
• Containerized microservices using AWS ECS or EKS (Kubernetes)

Database Layer:

• Amazon RDS for structured product/order data
• Amazon DynamoDB for fast cart & session handling

Authentication:

• Amazon Cognito for user login/signup & secure access

Payment Integration:

• Integrated via secure third-party APIs (Stripe/PayPal) with Lambda
• Logged into CloudWatch for monitoring

File Storage:

• Product images, invoices, user uploads stored in Amazon S3

Notifications & Email:

• Order confirmations & shipping alerts via Amazon SES & SNS

Monitoring & Alerts:

• Full observability with Amazon CloudWatch, X-Ray, and AWS Config

CI/CD Pipeline:

• Automated deployments via AWS CodePipeline, CodeBuild, CodeDeploy

Security & Compliance:

• IAM Roles, VPCs, Security Groups, and AWS Shield for DDoS protection
• Data encryption using KMS and access logs stored in CloudTrail
