Pierre Roman hosts an in-depth conversation with Will Gries about Azure Files Provisioned V2, detailing how this new billing model transforms cloud storage flexibility, performance, and cost predictability for Azure customers.

Unlocking Flexibility with Azure Files Provisioned V2

Host: Pierre Roman Guest: Will Gries, Principal PM, Azure Storage

Azure Files Provisioned V2 marks a significant evolution in Microsoft’s cloud storage solutions, much to the benefit of both new and seasoned Azure users. In this episode of E2E:10-Minute Drill, Pierre Roman explores with Will Gries how this updated billing and performance model enables a far greater degree of control and predictability for cloud storage infrastructure.

What Has Changed?

Previously, Azure Files offered a pay-as-you-go model (transaction-based) and a Premium (Provisioned V1) tier that sometimes required over-provisioning storage to meet IOPS needs. This could result in unpredictable costs and wasted resources.

Provisioned V2 changes the paradigm with:

  • The ability to provision storage, IOPS, and throughput independently.
  • A stable, predictable monthly bill based solely on what you reserve—no more per-operation fees.
  • No need to over-buy storage just to get higher performance.

Key Benefits

  • Cost Predictability: Users pay a known rate each month based on their reserved resources. This reduces bill surprises, even with fluctuating access patterns. Microsoft notes average cost reductions of 30–50% for active workloads relative to previous models.
  • Performance Scalability: Each share can now reach up to 50,000 IOPS and 5 GiB/sec throughput, supporting up to 256 TiB. You can dynamically adjust these parameters as needed—or even burst above your baseline for short intervals.
  • Simplified Management: Eliminates Hot, Cool, Transaction Optimized tiers—plan and budget with new per-share metrics and right-size your configuration. This is particularly advantageous for hybrid scenarios using Azure File Sync.

Why Shift to Provisioned V2?

  • Avoid over-provisioning and unpredictable variable charges.
  • Manage high-throughput, large-scale workloads or frequent access scenarios efficiently.
  • Improved transparency for IT budgeting and capacity planning.

Real World Example

A healthcare company with unpredictable spikes in access for medical images can now pre-provision exactly the throughput and storage needed, stay within budget, and use burst IOPS to handle peak loads without reconfiguring or incurring surprise transaction fees.

Conclusion

Provisioned V2 makes Azure Files a more enterprise-ready, cost-effective storage solution for dynamic workloads of all sizes. Whether optimizing hybrid storage strategies or modernizing legacy file sharing, this upgrade delivers both financial and operational control.
