About This Architecture

Microsoft Fabric Lakehouse Medallion Architecture unifies data ingestion, governance, transformation, and serving across Bronze, Silver, and Gold layers within OneLake's single storage fabric. Data flows from diverse sources—SQL databases, REST APIs, streaming events, ERP/SaaS, and IoT—through Data Factory pipelines and Eventstream into medallion-structured Delta tables, with security enforced via Microsoft Entra ID, sensitivity labels, DLP policies, and row/column-level security. Transformation occurs via Fabric Notebooks, Spark clusters, and Dataflow Gen2, while governance is maintained through Microsoft Purview auditing, data lineage, and business glossary integration across DEV, ACC, and PROD workspaces. The semantic layer leverages Power BI Direct Lake datasets with DAX measures and RLS models, serving insights to analysts, scientists, and BI consumers through reports, dashboards, APIs, and mobile apps.
