Infrastructure as Code

This study guide is designed to help IT professionals prepare for the Terraform Professional certification exam by covering all exam objectives in detail. It provides practical examples, tips, and best practices to master Terraform, a key tool for infrastructure as code, and validate your expertise in the competitive tech industry. Whether you're new to Terraform or an experienced user, this guide aims to enhance your skills and advance your career.

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.

Build a clear mental model of Kubernetes with illustrations, diagrams, small YAML examples, and practical kubectl commands. This beginner-focused guide connects core concepts to networking, storage, security, and everyday troubleshooting for systems engineers.

Want to use NixOS "for real" at work? Interested in learning one of the hottest emerging DevOps technologies? Jumpstart your professional career by reading this book authored by a professional user of NixOS.

Looking for ways to kick off your DevOps career? Let's go on a journey together to AWS cloud, Linux, containers, Kubernetes, IaC, and CI/CD pipelines.

Your infrastructure isn't a place anymore, it's text in a repo. This book teaches security engineers to read, review, and audit Terraform like an auditor, not a builder, so you know exactly what to look for before someone else's code hits production.

Learn Terraform through visual explanations of configuration, state, dependencies, providers, modules, and infrastructure workflows.

Learn Packer through visual explanations of repeatable machine images, templates, builders, provisioning, and image delivery.

Understand Argo CD and the GitOps model through clear diagrams and practical examples. Learn how reconciliation, sync policies, application health, access controls, and troubleshooting fit together.

Build a clear foundation for reliable Ansible automation. Visual explanations connect inventories, playbooks, variables, roles, validation, and safe operations to everyday systems engineering.

When critical infrastructure degrades, customer-facing applications continue blindly routing users into broken flows because modern architectures lack a dedicated layer for runtime coordination. This book introduces the Operational State Control Plane (OSCP)-formalizing the contracts, distribution mechanics, and zero-network resilience required to govern multi-surface application behavior during active incidents. A practical blueprint for platform architects, principal engineers, and SRE leaders running distributed production estates.

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.

What if S3 could be more than a place to put files? Build databases, queues, event logs, Git systems and distributed applications directly on object storage. Through production-grade Go implementations, this book explores what works, what breaks and how to design reliable systems around the real guarantees of S3-compatible storage.

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.

Master Terraform from your first configuration to production infrastructure at scale. Learn through practical examples, real cloud scenarios and proven patterns for building secure, reliable infrastructure. Go beyond the syntax to understand the decisions, trade-offs and workflows that help teams use Terraform with confidence.
