To ensure that your Infrastructure as Code (IaC) changes are safe before applying them, you should implement a robust validation and testing process. This involves using tools and practices that allow you to simulate and verify changes in a controlled environment, ensuring they meet your requirements and do not introduce errors or security vulnerabilities.

Example Concept: Implement a pre-deployment validation pipeline that includes static code analysis, unit testing, and plan previews. Use tools like Terraform's `terraform plan` to preview changes, and integrate static analysis tools such as `tflint` or `checkov` to catch potential issues early. Additionally, employ test frameworks like `terratest` to run automated tests against your infrastructure code, ensuring that changes behave as expected before they are applied to production environments.

Additional Comment:

Use version control systems like Git to manage IaC changes and enable code reviews.
Incorporate automated testing in your CI/CD pipeline to validate changes continuously.
Leverage feature flags or blue-green deployments for safer rollouts.
Regularly update your IaC tools and libraries to benefit from security patches and new features.
