Complementary Technologies
Scaling Considerations
Node.js scales horizontally well. Use clustering or container orchestration for multi-core utilization. Consider serverless for variable workloads.
Security Considerations
Validate all inputs, use helmet for security headers, implement rate limiting, keep dependencies updated, use npm audit regularly.
Performance Optimization
Use streaming for large files, implement connection pooling, cache aggressively with Redis, profile with clinic.js, optimize event loop usage.
Success Story
Series B real-time collaboration platform
Challenge
WebSocket server struggling with 10K concurrent connections. Frequent memory leaks causing crashes.
Solution
Fractional CTO redesigned architecture with proper connection management, implemented horizontal scaling, optimized event handling.
Result
Now handles 100K+ concurrent connections reliably. Memory usage reduced 60%. Zero downtime in 6 months post-launch.
Timeline: 3 months
Recommended Team Structure
JavaScript teams transition easily to Node.js. Typical backend team: 2-4 Node.js developers with infrastructure support.
