NGINX for Professionals

Stop configuring NGINX by superstition. Start reasoning about it like an engineer.

Most NGINX guides teach you to copy ten lines of configuration and call it done. This book teaches you why those ten lines work - the master/worker architecture, the event loop, the directive inheritance rules - so you can read any unfamiliar server block and predict exactly what it will do under load, under attack, and under failure.

Built from more than a decade of real production experience, NGINX for Professionals takes you from foundational architecture through the full stack of what a working engineer actually needs: reverse proxying and load balancing, TLS and security hardening, caching strategies, performance tuning, high availability, Docker and Kubernetes deployment, API gateway patterns, infrastructure as code, and production troubleshooting.

Inside you'll find:

• The master-worker architecture and event loop explained clearly enough to actually reason about performance
• Battle-tested reverse proxy and load balancing configurations, including the header and timeout details most tutorials skip
• A complete TLS hardening walkthrough, from certificate chains to OCSP stapling to mutual TLS
• Caching strategies that won't leak one customer's data to another - a real, documented category of production incident
• Real-world case studies drawn from production incidents: a flash sale that took down checkout, a cache that quietly leaked customer data, a certificate chain bug invisible to browsers
• A full chapter mapping PCI DSS, HIPAA, SOC 2, and GDPR requirements to concrete NGINX configuration

Whether you're a backend engineer handed "just add NGINX in front of it" as a one-line ticket, a site reliability engineer inheriting a tangle of server blocks nobody understands, or a platform engineer building repeatable infrastructure with Kubernetes or Terraform, this book gives you the mental model to configure NGINX with precision instead of guesswork.

Formatted for both Kindle and paperback, with complete, tested configuration examples throughout.
