When to Use Pay-As-You-Go
Variable & Temporary Workloads
- Development and testing environments that auto-pause on weekends.
- Short-term proof of concepts (PoC) under 3 months.
- Highly unpredictable seasonal bursts.
When to Use 1-Year Reserved
Production Enterprise Baseline
- Production Lakehouse, Data Warehouse, and Power BI capacities.
- Capacities running 24/7 background scheduled ETL jobs.
- Compare a reservation commitment with expected usage; actual savings depend on the applicable offer and utilization.

Frequently Asked Questions about Reserved Capacity
What is a Microsoft Fabric Reserved Instance?
A Microsoft Fabric Reserved Instance (RI) is an enterprise commitment to purchase Fabric Capacity Units (CUs) for a 1-year term. In exchange for this continuous commitment, Microsoft grants ~41% discounts compared to standard hourly Pay-As-You-Go rates.
Can I exchange or resize my Reserved Instance capacity?
Yes. Microsoft permits capacity exchanges and SKU upgrades within the Azure Portal, allowing organizations to scale up as their data workload demands grow.
Are Reserved Instances billed upfront or monthly?
Azure supports flexible monthly billing for 1-Year Reserved Instances at no extra interest charge, allowing you to pay the discounted rate month-by-month.
What happens if our workload exceeds the Reserved Instance capacity?
Any compute usage exceeding your Reserved CU baseline automatically spills over into standard Pay-As-You-Go rates, ensuring your applications never experience outages.
