TL;DRA growing e-commerce platform crashed during flash sales when traffic spiked 10x, with 30-minute manual scaling and 2-week releases. ConsultingCrafts rebuilt the AWS architecture with caching, CDN, RDS Multi-AZ, auto-scaling, and CI/CD, reaching 99.99% uptime during peak sales.
Key takeaways
- Problem: platform crashed during flash sales at 10x traffic; manual scaling took 30+ min and releases took 2 weeks.
- Bottlenecks: a single database instance strained checkout, with monitoring gaps that slowed incident root-cause analysis.
- Solution: EC2 Auto Scaling, ALB, ElastiCache Redis, RDS Multi-AZ with read replicas, and CloudFront CDN.
- CI/CD: CodePipeline with blue-green deployments enabled zero-downtime, weekly releases (up from bi-weekly).
- Results: 99.99% uptime during flash sales, 10x traffic capacity, and 5-minute auto-scale response time.
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
