Azure Policy helps to enforce organizational standards and to assess compliance at scale. With its policy definitions, it enables you to manage and enforce rules across your Azure resources, ensuring that they stay compliant with corporate and regulatory standards. Azure Policy evaluates resources in Azure by comparing the properties of those resources with business rules that are expressed as policies. While other services like Azure Advisor provide recommendations, and resource locks prevent modifications, they do not enforce compliance rules like Azure Policy does. Microsoft Purview relates to data governance across on-premises, multi-cloud, and software-as-a-service (SaaS) environments but not directly to policy compliance. Infrastructure as Code is a concept that automates the provisioning of infrastructures through code, which doesn't inherently provide compliance enforcement.
