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.
Whether you're upgrading, deploying, or simply exploring Ubuntu 26.04 LTS, this book is your essential guide to Canonical's most ambitious long-term support release. From installation and desktop features to security, performance, and enterprise deployment, it provides clear, practical coverage of everything you need to get the most from Ubuntu.
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.
What does it take to run an LLM on hardware that barely has enough memory to breathe? This practical guide takes you from transformer math and model compression to inference runtimes, benchmarking and real-world deployment, with hands-on case studies for building fully offline LLM systems on tiny devices.
Take a practical journey through SGLang, from its core architecture to real-world deployment and optimization. Built for engineers who need to run LLM inference reliably at scale, this handbook breaks down the tools, techniques and operational know-how needed to build and maintain production-ready SGLang systems.
Your old computers can run your house. Building it is a hands-on way to learn to work with an AI.
Building fast LLM inference is about far more than turning the right knobs. This book takes you inside vLLM and the systems behind it, showing how memory, scheduling, GPUs and distributed serving shape real-world performance. Learn how to measure what matters, find bottlenecks and build inference infrastructure that scales without wasting money.
MCP can transform the way you work with Claude Code. This practical guide takes you from the basics to production, showing you how to connect tools, build integrations, automate workflows and ship reliable, secure solutions you can use right away.
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.
Build secure, modern infrastructure with confidence. This hands-on guide shows you how to use Tailscale, WireGuard and zero-trust networking to create reliable, observable systems that scale. Follow practical, production-ready examples you can apply right away without guesswork or unnecessary complexity.
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.
Linux is one of the best decisions you can make for your computer — but knowing where to start is the hard part. This guide walks you through everything: choosing a distribution, installing it, and using it confidently every day. It was written by Jay LaCroix of Learn Linux TV, for complete beginners. No prior experience required.
1. Introduction to RHEL 10: Covers certification and RHEL fundamentals. 2. Key Features and Changes: Based on major updates like RDP replacing VNC, security improvements (post-quantum cryptography), and image creation tools. 3. Managing Systems: Extensive use of the RHEL Web Console for system tasks, software updates, and configuration. 4. Automation: Focus on RHEL System Roles for consistent system management. 5. Emerging Technologies: Cloud environments, containers, and experimental previews to explore.
Build your TCP/IP foundation through clear diagrams of layers, addressing, routing, transport, and end-to-end network communication.
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.
