How We Built for Speed, Stability, and Growth
In today’s fast-paced supply chain ecosystem, logistics platforms need to handle large volumes of data, real-time updates, and sudden traffic spikes — all without compromising performance. At TechVraksh, we tackled exactly that challenge using a powerful backend combination: Node.js and AWS.
⚙️ The Challenge
A logistics client needed a scalable, event-driven platform to:
-
Handle real-time shipment tracking
-
Process millions of data points from IoT-enabled devices
-
Auto-scale during peak load (festive seasons, flash sales)
-
Ensure high availability and fault tolerance
🧩 Why Node.js + AWS?
Node.js
-
Non-blocking, asynchronous I/O – perfect for real-time updates
-
Fast event loop – ideal for high-concurrency tasks
-
Lightweight and fast for REST APIs and WebSockets
AWS
-
Elastic Load Balancing & Auto Scaling
-
AWS Lambda for event-driven microservices
-
DynamoDB + S3 for scalable storage
-
CloudWatch for performance monitoring
-
API Gateway for secure API endpoints
🔨 Our Tech Architecture
-
Backend: Node.js (Express + WebSocket)
-
Database: AWS DynamoDB
-
Caching: Redis
-
Queue Management: AWS SQS
-
CI/CD: GitHub Actions + AWS CodePipeline
-
Monitoring: AWS CloudWatch + Sentry
📈 The Results
✅ 99.99% uptime during high-traffic events
✅ Real-time updates for >1 million tracked shipments
✅ Reduced latency by 40%
✅ Auto-scaling improved performance by 3x
✅ Monthly cost optimized by 25% using AWS Lambda for micro-tasks
💡 Lessons Learned
-
Design stateless microservices for easier scalability
-
Use event-driven architecture for better modularity
-
Monitor everything — logs, metrics, and user events
-
Optimize Lambda functions and DynamoDB throughput to reduce costs
-
Caching is your best friend — especially for repeated queries
🚀 Conclusion
Node.js and AWS together proved to be a robust, cost-effective, and scalable solution for this logistics platform. Whether you’re modernizing legacy systems or building a greenfield logistics product, this stack provides both the speed of development and enterprise-grade scalability.
