This two-part blog post introduces Infrastructure as Code (IaC) as a solution for managing cloud infrastructure efficiently. The first part explains the challenges of manually configuring cloud environments, such as human errors, lack of version control, and difficulty tracking changes. IaC addresses these issues by defining infrastructure programmatically, enabling automation, version control, and repeatability. The post highlights tools like Terraform, Pulumi, and cloud-specific options like Google Cloud Deployment Manager and AWS CloudFormation. It also discusses integrating IaC with CI/CD pipelines for automated deployments.

The second part provides a practical guide to using Terraform with Google Cloud Platform. It walks through installing necessary tools, creating a Google Cloud project, setting up service accounts, and deploying a virtual machine. The post demonstrates Terraform’s plan and apply workflow, showing how it detects and corrects unauthorized manual changes, and concludes with resource cleanup instructions.
