Microsoft Fabric eliminates multi-vendor complexity through a single SaaS platform built on OneLake, a unified storage layer where all data engineering, warehousing, and BI workloads natively read and write to the same open-source Delta Parquet files without data movement. By abstracting away complex network peering and infrastructure setup, it replaces fragmented vendor clusters with a single, dynamically shared pool of Fabric Capacity and propagates a universal security and governance model automatically across all workloads.
