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
