E-Commerce Microservices
A scalable e-commerce backend built with microservices architecture, handling thousands of concurrent users.
Overview
This project aimed to rebuild a monolithic e-commerce application into a robust microservices architecture. It handles user authentication, product catalog, inventory management, and order processing across independently deployable services.
Challenges
- 1
Ensuring data consistency across distributed services without distributed transactions.
- 2
Managing complex service-to-service communication and mitigating network failures.
- 3
Optimizing database query performance for high-traffic endpoints.
Architecture & Strategy
The system uses an API Gateway routing requests to specialized services. Event-driven architecture with RabbitMQ ensures loose coupling, while Redis caches frequent read operations.
Results
Reduced average response time by 40% under peak load.
Achieved 99.99% uptime during promotional events.
Improved deployment time from hours to minutes per service.
Lessons Learned
- The complexity of microservices should not be underestimated; robust CI/CD and observability are prerequisites.
- Eventual consistency is often an acceptable trade-off for higher availability.
- Thorough load testing is critical before migrating production traffic.
