ABOUT THE CLIENT
A growing e-commerce platform with performance issues during peak traffic and sales events.
THE CHALLENGE
- Platform crashed during flash sales with 10x normal traffic causing significant revenue loss
- Manual scaling process took 30+ minutes leaving customers frustrated during peak periods
- No CI/CD pipeline meant 2-week release cycles and slow response to production bugs
- Single database instance became bottleneck during high-traffic checkout processes
- Lack of monitoring visibility made root cause analysis difficult after incidents
THE SOLUTION
Optimized architecture with caching, CDN, database optimization, and auto-scaling.
- CloudFront | ElastiCache Redis | RDS Read Replicas | Auto Scaling | ALB | X-Ray & CloudWatch
Technical Implementation
- Implemented EC2 Auto Scaling groups with target tracking policies based on CPU and request count
- Configured Application Load Balancer with connection draining and health check optimization
- Built CodePipeline CI/CD with blue-green deployments for zero-downtime releases
- Deployed ElastiCache Redis cluster for session management and product catalog caching
- Set up RDS Multi-AZ with read replicas for checkout and reporting query separation
- Implemented CloudWatch dashboards with custom metrics and PagerDuty alerting integration
