The document presents an introduction to the benefits of using Terraform for infrastructure as code (IaC), emphasizing its reproducibility, time-saving capabilities, and reduction of human error. It outlines the evolution of IaC practices from the 2000s to the 2020s, advocating for the use of HashiCorp's tools, with a focus on CI/CD integration and modular configuration. Additionally, it includes examples of code for managing cloud resources and a case study on best practices.
