Infra As Code - Terraform - DevOps

Clique aqui para ver a versão em Português.

📄 Project

Infrastructure as Code (IAC) project, creating basic resources and advancing to more complex structures. Datasources, modules, and outputs were covered to facilitate maintenance. Cluster state management was also applied, and multiple providers were configured to create additional resources.

The purpose is to use Cloud Providers' consoles only for reading and to pass through IAC for any resource changes, keeping what is in code as the single source of truth. And to automate infrastructure across any Cloud Provider.
