System Administrators Bundle

This book takes you from the fundamentals of how a Linux operating system is assembled to the point where you can independently design, build, maintain, and publish your own distribution. You will learn what every major component does under the hood, why different distributions make different choices, and how to make those same choices for your own system. By the end, you will have built a bootable custom Linux distribution from source code, complete with a package management infrastructure, bootloader configuration, and installation media. Whether you are a system administrator building a hardened server image, a developer who needs a deterministic build environment, or an enthusiast who wants full control over every byte on disk, this book gives you the knowledge and the practical tools to do it.

This book takes you from your very first Ansible playbook through production-grade enterprise automation across hybrid multi-cloud environments. Whether you are a system administrator just discovering infrastructure as code, a DevOps engineer looking to deepen your automation skills, or a platform architect designing large-scale automation strategy, every chapter builds progressively on the last with practical, production-ready examples you can adapt immediately. You will learn not only how Ansible works but why it works that way, what patterns succeed in real organizations, and which anti-patterns to avoid. By the end, you will be able to design, implement, test, secure, and scale Ansible automation across VMware, bare metal, containers, Kubernetes, and every major cloud provider.

This is a comprehensive guide to Kubernetes administration, written for practitioners who already understand the basics and are ready to take ownership of clusters in production. It covers architecture deep dives, installation methods, networking, storage, security, observability, GitOps, multi-cluster management, cost optimization, and emerging trends. Every chapter includes hands-on examples, configuration samples, operational checklists, and real-world patterns drawn from production environments. Whether you are running a handful of nodes or managing a fleet of hundreds of clusters, this book gives you the knowledge to design, deploy, secure, and operate Kubernetes at scale.

This is a complete guide to administering PostgreSQL in production environments. Whether you are deploying your first database server or managing a fleet of high-availability clusters, this book walks you through everything from architecture internals and installation to security hardening, backup and recovery strategies, replication setups, performance tuning, and automated operations. It covers PostgreSQL 17 and 18 (the latest stable releases as of mid-2026) with practical examples, real-world configurations, hands-on labs, and production-tested best practices drawn from the official documentation and community expertise.

Server automation has evolved far beyond cron jobs and shell scripts. In 2026, the infrastructure engineer's toolkit spans SSH libraries, cloud SDKs, GitOps control planes, chaos engineering frameworks, and AI-assisted coding agents. This book is a comprehensive, production-focused guide for intermediate to advanced practitioners who want to build scalable, resilient, and secure automation architectures using Python. From Fabric and Ansible Python APIs through boto3, Azure SDK, and Google Cloud client libraries, from immutable infrastructure pipelines through GitOps workflows, self-healing systems, chaos engineering, and AI-augmented development, every chapter delivers practical code examples, error handling patterns, performance optimization techniques, and real-world case studies reflecting the emerging industry landscape of 2026. Whether you are an individual developer modernizing your infrastructure workflows or part of an enterprise team building automation at scale, this book provides the depth and breadth you need to operate confidently in today's hybrid, cloud-native, AI-informed world.
