\ud83c\udfaf Best Practices for Terraform Tagging<\/strong><\/h2>\n\n\n\n
    \n
  1. Enforce Standard Tags<\/strong> \u2013 Use terraform.tfvars<\/code> or locals {}<\/code> for consistent tagging.<\/li>\n\n\n\n
  2. Use Required Tags in Terraform Modules<\/strong> \u2013 Define common tags inside locals {}<\/code>.<\/li>\n\n\n\n
  3. Apply Tags at Scale<\/strong> \u2013 Use AWS Organizations or Azure Policies to enforce tagging.<\/li>\n\n\n\n
  4. Use CI\/CD to Validate Tags<\/strong> \u2013 Integrate tfsec<\/code> or OPA<\/code> to ensure mandatory tagging.<\/li>\n\n\n\n
  5. Implement Cost and Compliance Tags<\/strong> \u2013 Essential for FinOps tracking and cost allocation.<\/li>\n<\/ol>\n\n\n\n
