 ## What is policy as code?
 
-Policy as code applies software engineering practices to infrastructure policies. Instead of manually configuring compliance rules through cloud provider consoles or maintaining policy documentation in wikis, you write policies in programming languages and manage them alongside your infrastructure code.

 This approach provides several key benefits:
 
-**Cost control**: Define policies based on resource pricing to prevent expensive deployments before they happen. Set spending limits, identify unused resources, and enforce tagging for cost tracking and allocation across teams.

-**Compliance and security**: Enforce guardrails that prevent common misconfigurations like public S3 buckets, exposed databases, or overly permissive security groups. Apply consistent security standards across development, staging, and production environments.

-**Early validation**: Catch policy violations during `pulumi preview` before resources are created, not after deployment. This prevents non-compliant infrastructure from reaching production and reduces the time and cost of remediation.

-**Best practices as code**: Encode organizational standards and cloud provider best practices as versioned, testable policies. Share policy packs across teams to ensure consistent infrastructure patterns throughout your organization.
