+Azure offers the ability to boost disk storage IOPS and MB/s performance, this is referred to as bursting for both virtual machines (VM) and disks. You can effectively use VM and disk bursting to achieve better bursting performance on both your VMs and disk.
 
 Bursting for Azure VMs and disk resources aren't dependent on each other. You don't need to have a burst-capable VM for an attached burst-capable disk to burst. Similarly, you don't need to have a burst-capable disk attached to your burst-capable VM for the VM to burst.
 
 ## Common scenarios
 The following scenarios can benefit greatly from bursting:
-- **Improve startup times**  – With bursting, your instance will startup at a faster rate. For example, the default OS disk for premium enabled VMs is the P4 disk, which is a provisioned performance of up to 120 IOPS and 25 MBps. With bursting, the P4 can go up to 3500 IOPS and 170 MBps allowing for startup to accelerate by up to 6X.

With bursting, the P4 can go up to 3500 IOPS and 170 MB/s allowing for startup to accelerate by up to 6X.
 - **Handle batch jobs** – Some application workloads are cyclical in nature. They require a baseline performance most of the time, and higher performance for short periods of time. An example of this is an accounting program that processes daily transactions that require a small amount of disk traffic. At the end of the month this program would complete reconciling reports that need a much higher amount of disk traffic.
 - **Traffic spikes** – Web servers and their applications can experience traffic surges at any time. If your web server is backed by VMs or disks that use bursting, the servers would be better equipped to handle traffic spikes.

 For shared premium SSD disks, in addition to cost of the disk's tier, there's an extra charge that increases with each VM the SSD is mounted to. See [managed disks pricing](https://azure.microsoft.com/pricing/details/managed-disks/) for details.
 
-Ultra disks don't have an extra charge for each VM that they're mounted to. They're billed on the total IOPS and MBps that the disk is configured for. Normally, an ultra disk has two performance throttles that determine its total IOPS/MBps. However, when configured as a shared ultra disk, two more performance throttles are exposed, for a total of four. These two additional throttles allow for increased performance at an extra expense and each meter has a default value, which raises the performance and cost of the disk.

 You can adjust ultra disk IOPS and throughput performance at runtime without detaching the disk from the virtual machine. After a performance resize operation has been issued on a disk, it can take up to an hour for the change to take effect.
