Overview
A custom-built API gateway designed to handle high-throughput traffic for microservices architectures. Features intelligent request routing, adaptive rate limiting, circuit breaker patterns, and comprehensive observability.
Architecture
- Routing Engine: Trie-based path matching with weighted load balancing
- Rate Limiter: Token bucket algorithm with Redis-backed distributed state
- Circuit Breaker: Configurable failure detection with automatic recovery
- Observability: Prometheus metrics, distributed tracing, and Grafana dashboards
Key Achievements
- Handles 25,000+ requests/sec with p99 latency under 5ms
- Zero-downtime deployments via Kubernetes rolling updates
- Reduced service-to-service latency by 60% through connection pooling
- 99.99% uptime over 12 months of production operation
