Disk Bursting

When to use this skill

• Spiky IO workloads
• Boot storms

Key concepts

• Credit-based — P30 and smaller; accumulate credits when below baseline, burst up to 3,500 IOPS / 170 MBps.
• On-demand — P30+ opt-in, pay-per-use bursting beyond provisioned tier.
• Burst telemetry visible in Azure Monitor disk metrics.

Common pitfalls

• Counting on credit burst for sustained load — credits exhaust in minutes.
