SecureScalr – AWS Powered E-Commerce Solution
Overview
SecureScalr is a production-validated, secure multi-tier e-commerce architecture on AWS. It demonstrates how to design a scalable, resilient, and secure cloud system from the ground up — applying least-privilege IAM, encrypted data stores, edge protection via WAF, and Well-Architected Framework principles throughout.
The Challenge
Design a cloud architecture that passes the AWS Well-Architected Framework review, sustains real load (55K+ requests), blocks simulated attacks, and applies defense-in-depth at every layer — from the edge to the database.
The Solution
Built a multi-tier architecture with private EC2 application tier hidden behind a public ALB + Auto Scaling Group. Multi-AZ RDS ensures database availability during zone failures. CloudFront caches and serves S3 static assets at edge. WAF rules block common attack patterns (SQLi, XSS, rate abuse) before traffic reaches EC2. ACM provides TLS termination. IAM roles enforce least privilege per tier. Secrets Manager handles all credential rotation.
Tech Stack
Outcomes
- ▸55,000+ JMeter requests sustained under load testing without degradation
- ▸1,500+ simulated malicious requests blocked by WAF rules
- ▸AWS Well-Architected Framework review passed across all 6 pillars
- ▸Multi-AZ RDS failover validated — zero data loss during simulated AZ outage
