Which Azure service provides a unified data governance solution?

Azure Purview is the service that provides a unified data governance solution within Azure. It is designed to help organizations manage their data governance lifecycle by providing a way to discover, classify, and manage their data assets across the entire data estate.

With Azure Purview, organizations can gain insights into where their data resides, how it is used, and ensure compliance with data regulations. It enables businesses to maintain a clear understanding of their data landscape, which is crucial for making informed decisions about data management and compliance. By centralizing metadata and providing powerful search and classification capabilities, Azure Purview empowers data stewards and governance teams to enforce policies and improve data quality across various data sources.

Other options, like Azure Data Factory, focus on data integration and transformation, while Azure Blob Storage and Azure Data Lake Storage are primarily storage solutions. These services do not have the comprehensive governance capabilities that Azure Purview offers, making it the correct choice for a unified data governance solution.
