The application running on the virtual machine makes a request that requires 10,000 IOPS to the virtual machine. But, the same logic applies to throughput. To make these examples easy to follow, we'll only look at IOPS. Let's run through a couple of examples to clarify this concept. This can lead to negative consequences like increased latency. When capped, the application experiences suboptimal performance. Your application's performance gets capped when it requests more IOPS or throughput than what is allotted for the virtual machines or attached disks.
The disks have their own IOPS and throughput limits. OS disks and data disks can be attached to virtual machines. How does disk performance work?Īzure virtual machines have input/output operations per second (IOPS) and throughput performance limits based on the virtual machine type and size. It also describes how you can diagnose bottlenecks for your disk IO and the changes you can make to optimize for performance.
This article helps clarify disk performance and how it works when you combine Azure Virtual Machines and Azure disks. Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale sets
