Master Kong API Gateway with a practical guide that takes you from core architecture to advanced AI-powered API management. Learn to build secure, scalable platforms with production-ready examples, explore Kubernetes, decK and Terraform workflows, and discover how Kong AI Gateway enables intelligent LLM routing, semantic caching, guardrails and cost optimization across modern AI applications.

Apache APISIX is redefining what an API gateway can do in the age of AI. This hands-on guide takes you from the fundamentals to production-ready deployments, showing you how to build secure, scalable, and intelligent gateways for APIs, microservices and AI applications. With practical examples, you will gain the skills to confidently deploy, manage and optimize modern API infrastructure.

Learn Bash the way it should be taught: by building one real, tested backup tool — not toy examples — one Git commit at a time.

It's a practical book. We're going to build something real together, a University API, and we're going to grow it chapter by chapter until it looks like a system you'd be proud to deploy. We'll start with a few endpoints, give it databases, make it concurrent, lock it down with authentication, wrap it in containers, and finally split it into cooperating services that talk over the network.

Here's a shorter version:Go beyond DNS lookups and build a high-performance recursive DNS resolver in Zig from the ground up. Through a hands-on implementation, you will master the protocols, algorithms, and systems programming techniques that power one of the internet's most essential services.

Offensive Security with Kali Linux is a practical guide to ethical hacking and penetration testing, taking you from foundational Linux and networking concepts to advanced exploitation techniques. With a strong emphasis on ethical practice and real-world methodology, you'll learn to identify vulnerabilities, assess systems responsibly, and strengthen security using Kali Linux.

Design, build, and operate a Cisco SD-Access campus fabric — greenfield and brownfield — through one realistic, end-to-end project.

Stop memorizing networking concepts—start understanding how real networks work. This book takes you from network architecture and TCP/IP fundamentals to routing, switching, wireless security, common cyber attacks, and defense-in-depth strategies. Perfect for students, IT professionals, and anyone beginning a career in cybersecurity.

Build your own 24/7 internet radio in a single weekend — on a €5 server, understood down to the last line. Ten chapters from bare server to on-air: the tower (Icecast), the robot (Liquidsoap), the door (nginx). Every step tested live, every trap marked. Friday it's a napkin sketch; Sunday night a stranger presses play, and it plays.

Anyone can turn on SD-WAN. Far fewer can design it, migrate a live network onto it without an outage, steer voice and cloud traffic intelligently, prove it's secure to an auditor, and still sleep at night. SD-WAN Fundamentals follows one company through the whole journey — design, build, migrate, secure, operate — so you learn SD-WAN the way you'll actually use it: as a project, end to end.

Most developers can build a web server with a framework. Far fewer understand what happens underneath. Rust from Sockets to Servers takes you from raw TCP sockets to a production-ready web server built in Rust, giving you a deep understanding of HTTP, async programming, TLS, routing, and the foundations behind every modern web application.

Build a production-grade BitTorrent client in Python from the ground up while exploring the protocols, networking concepts, and engineering decisions behind one of the internet's most successful peer-to-peer systems. From peer discovery to data transfer, you'll implement every major component and gain a practical understanding of how BitTorrent works in the real world.

Pass the Cisco 200-201 exam and start thinking like a SOC analyst — even if you've never read a packet capture in your life. Every blueprint topic explained from first principles, with runnable examples, exam tips, and 125 practice questions.

New to network automation? This beginner-friendly guide turns the entire Cisco 200-901 exam into plain English. Six chapters, 28 lessons, and 140 Cisco-style practice questions — every concept explained with an everyday analogy before the technical detail. Go from "what even is a network?" to writing real Python that talks to Cisco APIs. Start passing, not panicking
