Terraform Best Practices

Structure

• Use modules for reusable infrastructure
• Separate environments with workspaces or directories
• Use terraform.tfvars for environment-specific values
• Keep state remote (S3 + DynamoDB, Terraform Cloud)
• Use consistent naming conventions

Code Quality

• Use terraform fmt and terraform validate
• Use tflint for additional checks
• Pin provider versions
• Use for_each over count for resources
• Use locals for computed values
• Tag all resources
