Why You Need a Fabric Sizing & TCO Assessment

Migrating to Microsoft Fabric is not just a technical upgrade—it reshapes your entire cloud economics, governance posture, and real-time analytics velocity.

1. Capacity Sizing & Smoothing

Fabric introduces 24-hour background smoothing and burst capacity. Over-provisioning wastes budget; under-provisioning triggers throttling.

2. P-to-F License Transition & TCO

Power BI Premium (P1-P5) is retiring. Moving to Fabric F-SKUs unlocks 1-year and 3-year Reserved Instances (RI) and automatic capacity pausing.

3. DirectLake vs. Import Mode

DirectLake queries parquet files directly on OneLake at memory speeds, eliminating scheduled dataset refreshes while respecting memory guardrails.

4. Governance & Fabric IQ AI Readiness

Audit your Entra ID tenant settings, Copilot capacity token consumption, and unified OneLake security domains before rolling out to business users.

Fabric Assessment FAQ

Clear answers to common enterprise Microsoft Fabric migration and capacity sizing questions.

Fabric F64 provides the exact equivalent compute power of Power BI Premium P1 (64 Capacity Units). However, F64 includes access to the entire Fabric ecosystem (Lakehouses, Synapse Data Engineering, Real-Time Analytics, Data Factory, and Copilot) with the ability to pause and scale compute elastically.
