This book is more than just a learning resource; it's a powerful tool that will empower you to create, manage, and scale up robust, efficient, and automated cloud infrastructures, no matter the size of your environment or your current level of expertise. This is a definitive guide designed to take you on an illuminating journey through the landscape of Infrastructure as Code (IaC), with Terraform as your trusted ally. Just as developers write code to create software applications, IaC allows us, the IT and DevOps folk, to codify our infrastructure. In simpler terms, IaC is the practice of managing and provisioning computing infrastructure with machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. This book aims to provide a foundation for professionals of all levels, starting from the basic principles of IaC, to the intricate functionalities and capabilities of Terraform. Each chapter of the book is strategically structured to gradually build your understanding and proficiency in handling Terraform.
