E-Commerce Platform - Complete DevOps Pipeline

Author: Davido Assignment 7: Complete End-to-End DevOps Pipeline

A production-ready e-commerce platform with complete DevOps automation deployed on AWS. This project demonstrates comprehensive DevOps skills across infrastructure, CI/CD, security, monitoring, and automation.

• Primary Region: us-east-1 (production)
• DR Region: us-west-2 (standby with cross-region RDS replica)
• Compute: Amazon EKS (Kubernetes) with managed node groups
• Database: Amazon RDS PostgreSQL with read replica
• Caching: Amazon ElastiCache (Redis) for session management
• CDN: Amazon CloudFront with WAF integration
• Messaging: Amazon SQS/SNS for event-driven architecture
• Security: AWS WAF, Shield Standard, Secrets Manager, RBAC
• GitOps: ArgoCD for declarative Kubernetes deployments

The GitHub Actions pipeline (.github/workflows/pipeline.yaml) automates:

1. Build & Test - npm test for all services
2. Container Build - Docker build + push to ECR
3. Security Scan - Trivy vulnerability scanning
4. Blue-Green Deploy - Rolling update to EKS
5. Health Verification - Post-deploy health checks
6. Auto-Rollback - Automatic rollback on failure
