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.

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.

The complete, blueprint-faithful study guide to Cisco's DCNAUTO 300-635 v2.0 exam. All 26 topics in Cisco's own order and wording, 26 original diagrams, 190 practice questions, a timed practice exam and a 13-lab guide you can run for free.

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.

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.

Everything you need to pass the 300-215 DFIR exam — all five domains, 18 original diagrams, and 159 practice questions — in one clear, unofficial study guide.

Practical, safe AI for people who actually run networks.
