Infrastructure as Code with Terraform: Best Practices

Infrastructure as Code (IaC) with Terraform brings the same rigor to infrastructure that version control brings to code.

Organize your Terraform code into modules. Use workspaces for environment separation. Store state remotely in S3 with DynamoDB locking. Always plan before apply.

Best practices: keep modules small and focused, use data sources instead of hardcoding, implement automated validation in CI, and use Terraform import for existing resources.
