Network Proxy Bundle

This book is a comprehensive guide to designing, deploying, and operating HAProxy in production environments. It moves from first principles through advanced engineering topics, explaining not just how to configure HAProxy but why each feature exists, how it interacts with other components, what can go wrong, and how to build reliable systems around it. Every configuration example is complete, valid, and designed for real-world use.

The primary reference version for this book is HAProxy 3.4 LTS. Where behavior differs from earlier stable versions, especially 2.8 LTS, this is explicitly noted. HAProxy Enterprise-specific capabilities are distinguished from the open-source Community Edition wherever the difference matters for architecture or configuration.

Envoy Proxy has become the foundational data plane for modern cloud-native infrastructure, powering service meshes, API gateways, edge proxies, and increasingly, AI inference platforms. This book provides a comprehensive, production-focused guide to understanding, deploying, and operating Envoy at scale. Beginning with core architectural concepts and progressing through advanced traffic management, security, observability, and extensibility patterns, every chapter delivers detailed explanations alongside real-world configuration examples. A dedicated section covers modern AI and LLM workloads, including multi-provider routing, intelligent model selection, streaming responses, cost optimization, and inference-specific observability. Whether you are a platform engineer building service meshes, an SRE operating critical infrastructure, or an architect designing AI-native systems, this book equips you with the depth needed to use Envoy effectively in production environments.

This book is a comprehensive technical reference for intermediate Linux administrators through advanced DevOps and platform engineers who need deep operational knowledge of NGINX. It covers the complete ecosystem from core architecture and configuration fundamentals through load balancing, caching, TLS termination, HTTP/2 and HTTP/3, Kubernetes integration, performance tuning, security hardening, and production operations. Every concept is explained with technical rigor: not just how features work but why they exist, when to use them, their tradeoffs, performance implications, and common pitfalls. Production-ready configuration examples are provided throughout, annotated line by line, so you can understand the reasoning behind each directive.
