The definitive technical reference for backend engineers and platform teams designing, configuring, and operating API gateways in distributed systems.
Covering Kong, Envoy, Tyk, NGINX Plus, AWS API Gateway — from fundamentals to production-scale patterns.
Modern distributed systems place the API gateway at the critical ingress boundary — the control point for north-south traffic, security policy enforcement, and backend contract abstraction. Getting gateway architecture right determines the operational ceiling of your platform: from startup-scale monoliths to multi-cluster, multi-region deployments serving millions of requests per second.
This reference covers the full spectrum: selecting the right gateway technology for your use case, designing resilient middleware pipelines, implementing authentication and rate-limiting at scale, and mastering advanced routing patterns including multi-tenant isolation, API versioning, and JWT/API-key-based traffic segmentation.
Every topic includes production-ready configuration examples, trade-off analyses, and architectural decision frameworks validated against real-world deployments on Kong Gateway, Envoy Proxy, AWS API Gateway, NGINX Plus, and Tyk.
Three structured sections take you from core gateway concepts through middleware chain design to advanced routing strategies.
Core architectural patterns, deployment models, control-plane vs. data-plane separation, gateway selection criteria, security boundaries, high-availability topologies, and capacity planning.
Phase-based pipeline architecture, authentication proxying, JWT validation, rate limiting, Redis backends, CORS configuration, caching strategies, and request/response transformation.
L7 header inspection, regex-based path matching, JWT-claim and API-key routing, multi-tenant namespace isolation, cross-cluster traffic steering, and API version lifecycle management.
