Preface The way we build, deploy, and manage IT infrastructure has changed dramatically over the years. From manually configuring servers in physical data centers to automating cloud environments with just a few lines of code, the journey of infrastructure management has been nothing short of revolutionary. This book, Infrastructure Automation with Pulumi and TypeScript, is a guide to embracing this transformation by adopting Infrastructure as Code (IaC) principles and leveraging Pulumi, a modern platform that makes cloud infrastructure management more efficient and intuitive. Pulumi stands out from traditional IaC tools by allowing you to use familiar programming languages like TypeScript, Python, and Go instead of domain-specific languages. This opens up new possibilities for developers and infrastructure engineers to collaborate seamlessly. By combining the power of TypeScript with Pulumi’s capabilities, this book aims to simplify the often-complex process of managing cloud infrastructure. Cloud computing has become the backbone of modern IT systems. However, managing cloud infrastructure manually or through scattered scripts can lead to inefficiencies, errors, and scalability challenges. Infrastructure as Code addresses these issues by treating infrastructure configurations as version-controlled, reusable code. This ensures consistency, repeatability, and agility in managing infrastructure across multiple environments. Pulumi takes this concept further by integrating IaC with modern programming practices. Whether you are a cloud architect, DevOps engineer, or developer, Pulumi empowers you to use your coding skills to automate infrastructure tasks while maintaining flexibility and precision. This book guides you step by step in mastering Pulumi and TypeScript for cloud automation.
