Avoid DirectQuery. Only consider alternatives if you absolutely had to. That world no longer exists. Today, Microsoft Fabric offers five different storage modes, each designed for a specific architectural purpose. Choosing the wrong one can impact performance, scalability, refresh times, capacity consumption, governance, and even the long-term success of your analytics platform. This isn't a feature comparison. It's an enterprise architecture decision. In this video, Ajay Kumar walks through the complete decision framework used to select the right Power BI and Microsoft Fabric Storage Mode for enterprise workloads. Using real consulting stories, practical architecture patterns, and a simple decision tree, you'll learn when to choose Import, DirectQuery, Dual/Composite, Direct Lake, or Aggregations + Composite, and more importantly, when you shouldn't. Whether you're designing Microsoft Fabric solutions, leading enterprise BI projects, or preparing for Fabric adoption, this framework will help you make storage decisions with confidence. In This Video, You'll Learn: • The 5 Power BI Storage Modes explained • Import vs DirectQuery vs Direct Lake vs Composite Models • The Enterprise Storage Mode Decision Tree • How to choose the right storage mode for your workload • The 4 Questions every Enterprise Architect should ask before building • When Import Mode is still the best choice • When DirectQuery becomes the right architecture • Direct Lake advantages and hidden cost considerations • Aggregations + Composite patterns for multi-billion-row datasets • Enterprise design principles that improve scalability and performance • Common architecture mistakes that lead to expensive redesigns • Real consulting stories from enterprise Microsoft Fabric implementations Down
