PostgreSQL Under Load shows what really happens when production gets busy. Learn how connections, transactions, MVCC, locks, WAL and autovacuum interact under pressure, then use that knowledge to diagnose incidents, tune PostgreSQL and build systems that stay reliable when concurrency spikes.

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.

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.

A recovery plan does not prove that recovery will work. This practical playbook helps IT teams plan, execute, evidence, and evaluate enterprise DR tests using structured workflows, decision controls, and reusable templates.

Infrastructure gets complicated fast. Mastering Terragrunt shows you how to bring order to growing Terraform and OpenTofu environments without adding unnecessary complexity. Learn practical patterns for managing multiple accounts, regions and teams, streamline deployments and build infrastructure that stays maintainable as your organization scales.

In this book, we plan before we act, we preview before we commit, we gate on evidence rather than on hope, and we write the recovery before we take the risk. By the time you get to the last chapter, you'll be familiar with the switches over NETCONF, server provisioning, building overlays, traffic inspection, cloud network provisioning, Kubernetes resource application, RDMA fabric validation, inference traffic routing, and reporting your findings through an interface that an assistant can query.

Take control of your storage with FreeCORE: The Complete Guide. From your first installation to advanced ZFS management, network shares, security, backups and performance tuning, this practical guide shows you how to build, manage and troubleshoot a reliable NAS with confidence, whether you are running a home lab or a production environment.

Shadow IT is everywhere, from unsanctioned apps to forgotten cloud resources. This practical guide shows IT and security teams how to find what they cannot see, assess the risks and put effective controls in place without slowing the business down. Packed with practical strategies, code examples and clear roadmaps, it turns Shadow IT from a hidden risk into something you can manage.

A practical guide to finding threats that never need to touch disk. Explore Windows internals, memory forensics, EDR telemetry and network detection through safe labs and real investigative methods. Built for defenders who want to understand what happens in memory, spot suspicious behavior and turn evidence into reliable detections.

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.

Cyber threats do not stop at the office network. When industrial systems are targeted, the consequences can reach far beyond lost data. This practical guide shows how to secure OT and critical infrastructure from the ground up, combining proven standards, real-world defenses and hands-on guidance for the systems that keep the world running.

Running NetBSD in production is one thing. Running it under serious traffic is another. NetBSD at Scale shows how to design, secure, tune and operate infrastructure built for real workloads. From architecture and automation to high availability and disaster recovery, it is a practical guide for engineers who need systems that keep working.

Take OpenTelemetry from theory to production. This practical guide shows you how to design, deploy and operate observability at scale, with real configurations, proven architecture patterns and hands-on guidance for performance, security, troubleshooting and cost. Built for engineers who need telemetry that works when it matters.

Master Kubernetes health checks from the basics to production-grade reliability. Learn how probes really work, troubleshoot failures fast and build applications that recover automatically. With practical YAML, real-world scenarios and proven reliability patterns, this guide helps you keep Kubernetes workloads healthy when it matters most.

Cloud networks rarely fail in obvious ways. A DNS lookup breaks, a route disappears or traffic vanishes somewhere between clouds. This book shows you how to understand what is really happening, build networks that hold up under pressure and troubleshoot failures with confidence across AWS, Azure, Google Cloud, Kubernetes and hybrid environments.
