  3. Environment Variable: New environment variable (default: "prod")
  4. Tags: New comprehensive tagging (backward compatible)

For New Deployments

  1. Recommended: Use Well-Architected Framework from start
  2. Configuration: Use terraform/well-architected/main.tf
  3. Security: Use enhanced Key Vault module with RBAC
  4. Cost Management: Set up budget alerts

Upgrade Path

Step 1: Update Terraform Configuration

cd terraform
terraform init -upgrade

Step 2: Review Variables
