Modern insurers require agile, integrated data systems to harness AI. This framework for a global insurer uses Azure Databricks to unify legacy systems into a governed lakehouse medallion architecture (bronze/silver/gold layers), eliminating silos and enabling real-time analytics. The solution employs: Medallion architecture for incremental data quality improvement. Unity Catalog for centralized governance, row/column security, and audit compliance. Azure encryption/confidential computing for data mesh security. Automated ingestion/semantic/DevOps pipelines for scalability. By combining Databricks’ distributed infrastructure with Azure’s security, the insurer achieves regulatory compliance while enabling AI-driven innovation (e.g., underwriting, claims). The framework establishes a future-proof foundation for mergers/acquisitions (M&A) and cross-functional data products, balancing governance with agility.
