High-Volume E-Commerce Platform Scaling

Optimizing for Black Friday traffic spikes and performance

Challenge

A growing e-commerce platform was experiencing performance bottlenecks during peak traffic periods, with response times exceeding 3 seconds and occasional timeouts during high-traffic events.

  • Monolithic Architecture
  • Single Database
  • No Caching Layer
  • Manual Scaling

Solution

We implemented a microservices architecture with event-driven communication, multi-tier caching, and auto-scaling infrastructure to handle traffic spikes seamlessly.

  • Microservices
  • Event Sourcing
  • Redis Cluster
  • Auto-scaling
  • CDN Integration

  • Custom Configurations

Solution

We implemented a hybrid tenant isolation model with row-level security, tenant-aware routing, and dynamic resource allocation based on usage patterns.

  • Row-level Security
  • Tenant Routing
  • JWT Claims
  • Resource Pools
  • Feature Flags
