Microsoft Purview provides a comprehensive data governance solution that helps organizations manage and govern their entire data estate, offering a unified view of data across on-premises, multi-cloud, and SaaS environments. This assists in maintaining data governance and ensuring compliance with various regulatory standards. Azure Policy, while also related to governance, is more focused on creating and enforcing rules for Azure resources rather than offering a holistic data governance solution. Azure Information Protection is a cloud-based solution that helps an organization classify and protect its documents and emails by applying labels, but it does not offer the wide-ranging governance capabilities of Microsoft Purview. Azure Service Health provides insights into the health status of Azure services and does not deal with data governance.
