Build Linux systems that do more than boot. This hands-on guide takes you from bootloader and kernel to secure updates, reproducible images, manufacturing and fleet operations. With runnable code and production-tested techniques, you’ll learn how to build Linux appliances designed for the real world.

Mastering Keepalived is a practical guide to building reliable, highly available infrastructure with VRRP, failover and health checking. Learn how to design, configure, troubleshoot and secure Keepalived in real production environments, from core networking concepts to advanced HA architectures and day-to-day operations.

From the Linux basics to advanced development workflows, this practical guide shows you how to turn Linux into a powerful software development environment. Learn the command line, work with popular programming languages, use containers and CI/CD, debug and profile applications and build skills you can use every day.

Memory is at the heart of Linux performance. This book explains how the kernel manages it from virtual memory and page allocation to NUMA, cgroups and real-world optimization. Learn through clear explanations, kernel source examples and practical exercises you can run yourself.

Whether you're deploying your first reverse proxy or managing high traffic production infrastructure, this book gives you the practical knowledge to use NGINX with confidence. Learn not just what each feature does but why it matters, how to avoid common mistakes and how to build fast, secure, reliable systems that scale.

When a license renewal lands at 567% of last year's bill, renting your infrastructure stops being a strategy. This is the escape tunnel: a complete production build of Apache CloudStack 4.22 LTS — KVM, Ceph, OS10 leaf-spine — across a three-city UK estate, written by an engineer with 32 years of building the real thing. Own your cloud down to the last packet.

Your old computers can run your house. Building it is a hands-on way to learn to work with an AI.

Most writing about AI and infrastructure stops at the demo. This book starts on the day the model is confidently wrong at 3 a.m. and an auditor asks who authorised the action it took. Seven working labs — MCP servers with real identity and audit, closed-loop remediation behind a reversibility gate, and autonomy that can be revoked — for platform engineers in safety-critical and regulated industries.

pen the chapter your team is struggling with. You will never think about an unpatched dam, a master key on a hook, or an alarm bell wrapped in a sock the same way again.

What really happens inside a database when queries run, data is stored and performance starts to suffer? This book takes you behind the scenes of SQLite, PostgreSQL and modern storage engines, showing how they work through real code, practical examples and performance analysis. Learn to find bottlenecks, make better design decisions and build faster, more reliable applications.

This book is for Go programmers who know a little networking, and for network engineers who know a little Go. There's no need to be an expert in either. So, in these chapters, we're building a tool together, Netkit, and it grows a bit more every time we solve a problem. And each chapter kicks off with a situation you might recognise, like a supplier recall, a partner network that's all over the place, or a backup that drags on for no good reason.

In this 2nd edition, I'm going to be working with you on a single app called OrderDesk. We'll build its inventory, roles and secrets, and then we'll patch its servers, provision its cloud resources and deploy it to Kubernetes. Later, we'll watch it with Prometheus, heal it with Event-Driven Ansible and diagnose its failures with playbooks that collect evidence in seconds. Then, in the last few chapters, we'll start inviting AI agents through tools and MCP servers, while approvals and check mode make sure that everyone keeps control of the decisions. You don't need to be a pro programmer to follow along.
