Hello Azure Community,
There’s a new capability in public preview that I believe many of you will find both practical and cost-efficient: Live Resize for Premium SSD v2 and Ultra NVMe Disks.
If you’ve ever had to scale storage mid-deployment — or worse, plan for peak storage needs months in advance “just in case” — this is a feature that changes the game. You can now dynamically expand disk capacity with zero downtimefor your applications.
Why This Matters
For most production workloads, storage planning is a balancing act between cost and scalability. With this update, Azure allows you to:
- Start with smaller disks to save on initial costs
- Resize them live, as your capacity requirements grow
- Avoid service disruptions or application downtime
- Eliminate the need for VM reboots or storage migrations
This applies to Premium SSD v2 (Pv2) and Ultra NVMe Disks, which are typically used for high-performance scenarios — think databases, analytics, or high-throughput services where every second of downtime has a cost.
When to Use It
I see this being especially useful for:
- Workloads with unpredictable growth (e.g. data ingestion, e-commerce, seasonal demand)
- Dev/test environments that transition to production
- Any situation where you want to pay-as-you-grow without operational headaches
And let’s be honest — who enjoys scheduling downtime for something as simple as a storage expansion?
If you’re managing performance-critical workloads or just want more control over your storage lifecycle, this new Live Resize feature is worth exploring. It’s the kind of enhancement that feels small but removes a big architectural constraint.
Have you tested it yet? Let me know your thoughts — curious to hear if it worked seamlessly for your scenarios.
Take care,
