Pulumi Infrastructure as Code: Automate Multi-Cloud Deployments and Modernize Your DevOps Workflow
K. Keeler, Robert
Synopsis "Pulumi Infrastructure as Code: Automate Multi-Cloud Deployments and Modernize Your DevOps Workflow"
Picture this: a small, quiet mistake made by hand, once, months ago. Nobody remembers making it. Nobody can explain why one server behaves differently from the other nine. This is configuration drift, and it has haunted infrastructure teams for decades. You are about to learn how to make that story impossible to repeat. Every chapter in this book was built around a real problem engineers actually face — the 2 a.m. page because nobody could review a change before it broke production, the "which cloud provider is doing what" confusion, the shared component nobody dared touch because nobody understood it. You won't just learn Pulumi's syntax. You'll learn why every feature exists, and exactly what it protects you from. What's Inside Getting started: CLI setup, projects, stacks, and your first real deployment Core concepts: resources, providers, Inputs and Outputs, and the dependency graph Building reusable components and sharing them as versioned packages Provisioning networking, compute, and storage across AWS, Azure, and Google Cloud Cross-cloud networking and hybrid architecture patterns Kubernetes clusters, Helm charts, and GitOps-adjacent workflows Testing, CI/CD pipelines, and policy as code with CrossGuard Drift detection, least-privilege security, and cost visibility at scale A full appendix: CLI reference, provider cheat sheets, troubleshooting, and a Terraform migration guide Who It's Meant For This book is written for you if: You already write code in at least one general-purpose language You're comfortable with basic cloud concepts, even without deep experience You've used Terraform, CloudFormation, or nothing at all — no prior Infrastructure as Code background required Whether you're an individual engineer or part of a growing platform team, this book meets you where you are and takes you somewhere considerably more capable. Every day you keep managing infrastructure by hand is another day closer to a mistake nobody can trace. The tools, the patterns, and the discipline you need are sitting in the next few hundred pages. Turn the page. Your infrastructure is waiting to be written properly — this time, in code you can actually trust.
