#Nexus API

A robust API management platform that serves as the backbone for a multi-service architecture. Features include intelligent request routing, automatic failover, comprehensive analytics, and developer-friendly documentation.

##The Challenge

Our client's monolithic API was buckling under growing demand. They needed a scalable gateway that could handle 500M+ monthly requests while maintaining sub-50ms latency across 12 global regions.

##Our Approach

###Phase 1: Gateway Architecture

We designed a distributed API gateway in Go, optimized for high throughput:

• Request routing: Intelligent load balancing with health checks
• Rate limiting: Adaptive algorithms that adjust to traffic patterns
• Caching layer: Multi-tier caching with 95% hit rate

###Phase 2: Global Distribution

Deployed across 12 regions with a custom cache invalidation protocol:

• Consistent hashing for request distribution
• Cross-region replication with eventual consistency
• Automatic failover with <1s detection time

###Phase 3: Developer Experience

Built a comprehensive developer portal:

• Interactive API documentation with live testing
• SDK generation for 5 programming languages
• Real-time analytics dashboard for API consumers

##Results

• 500M+ requests handled monthly
• 95% cache hit rate
• 12 global regions
• Zero downtime during deployments

##Technical Highlights

• Go-based gateway with gRPC internal communication
• Redis Cluster for distributed caching
• Prometheus + Grafana for real-time monitoring
• Terraform for infrastructure as code across all regions
