Generally available: Virtual Machine level disk bursting supports additional VM types

Published date: February 16, 2022

Virtual Machine level disk bursting supports M-series, Msv2-series Medium Memory, and Mdsv2-series Medium Memory VM families allowing your virtual machine to burst its disk IO and  throughput performance for a short time, daily. This enables VMs to handle unforeseen spiky disk traffic smoothly and process batched jobs with speed. There is no additional cost associated with this new capability or adjustments on the VM pricing and it comes enabled by default.

Some example scenarios where bursting can be applied:

  • Improve boot times: With your virtual machine and your disks both being able to burst and coming fully stocked with bursting credits at the start, your instance will be able to boot at a much faster rate than before. 
  • Handle batch jobs: Some application workloads are cyclical in nature, requiring a baseline performance for the majority of the time but a higher performance for a short period of time. For instance, an accounting program that processes daily transactions requiring a small amount of disk traffic but then monthly end reports which need a higher amount of disk traffic. 
  • Prepares for trafficspikes: Web servers and their applications can get a surge of traffic from unforeseen circumstances. With bursting virtual machines and disks backing the web servers, the web servers will handle traffic spikes smoothly and improve their customer’s experience by reducing load times under heavy stress.
