General availability: Change performance tiers for Azure Premium SSDs with no downtime

Published date: September 01, 2021

On Azure Premium SSDs, you can now change the performance tiers without any downtime to your application (generally available). You can change the performance tier of a disk even when it is attached to running virtual machines. For planned events like a seasonal sales promotion or running a training environment, you need to achieve sustained higher performance for a few hours or days and then return to the normal performance levels. With performance tiers on Premium SSDs, you have the flexibility to scale the disk performance without increasing the disk size by selecting a higher performance tier. You can also change tiers to bring it back to your baseline performance tier, enabling you to achieve higher performance and cost savings.
