# Microsoft Azure B-Series Virtual Machines
> Microsoft Azure B-Series Virtual Machines are a family of burstable VMs designed for workloads that typically run at a low-to-moderate baseline CPU performance but require high bursts of speed when demand spikes. They operate on a credit-based system where users accumulate CPU credits during periods of low usage to be spent during high-activity bursts.
