Azure infrastructure deployment using Terraform and GitHub Actions

A technical series outlines the implementation of automated infrastructure as code (IaC) workflows using Terraform, GitHub Actions, and Microsoft Azure. The process involves deploying complex infrastructure, including virtual networks (VNets), subnets, and virtual machines, across development, testing, and production environments.

Key components of the workflow include the use of environment-specific configuration files (.tfvars) to manage network settings and the implementation of remote state management within Azure storage accounts to secure sensitive data. To ensure stability, the workflow incorporates GitHub branch protection rules and Pull Request validation. This validation process allows for automated Terraform initialization and execution planning to identify configuration errors before any resources are deployed to Azure.
