OneLake Explained: Microsoft Fabric's Secret Weapon

OneLake is the foundation that makes Microsoft Fabric work - but most people don't understand what it actually does. In this video, I break down how OneLake eliminates data silos and why it represents a fundamental shift in data architecture. What you'll learn: - The data silo problem (why we copy data everywhere) - What OneLake is and how it actually works - Why Delta Lake format matters for interoperability - Real-world example: Before and after OneLake - Key benefits: cost, performance, governance, consistency - Honest limitations and considerations OneLake moves us from "copy data everywhere" to "write once, access anywhere" - a genuine architectural shift for modern data platforms.
