On-demand disk bursting for Azure Premium SSDs now generally available
Published date: 02 November, 2021
Today, we are announcing the general availabity of on-demand bursting on Azure Premium SSDs larger than 512 GiB or larger. Unlike the previous credit-based system where you can only burst if you have accumulated credits, our new on-demand bursting capability allows you to burst up to 6X (up to 30,000 IOPS and 1,000 MB/s of throughput) of the provisioned amount whenever needed. This provides you with the flexibility to scale performance to meet demand and optimize costs.
You can easily take advantage of on-demand bursting by enabling it on supported Premium SSD disks. You will pay for a burst enablement fee and burst transaction costs for the additional transactions beyond the provisioned target.
