The Bpsv2-series virtual machines are based on the Arm architecture, featuring the Ampere® Altra® Arm-based processor operating at 3.0 GHz, delivering outstanding price-performance for general-purpose workloads. These virtual machines offer a range of VM sizes, from 0.5 GiB to up to 4 GiB of memory per vCPU, to meet the needs of applications that don't need the full performance of the CPU continuously, such as development and test servers, low traffic web servers, small databases, micro services, servers for proof-of-concepts, build servers, and code repositories. These workloads typically have burstable performance requirements. The Bpsv2-series VMs provides you with the ability to purchase a VM size with baseline performance that can build up credits when it's using less than its baseline performance. When the VM has accumulated credits, the VM can burst above the baseline using up to 100% of the vCPU when your application requires higher CPU performance.

CPU Burst resources
1The base CPU performance metric hasn't changed. The updated (2024) numbers were normalized using a 0 – 100% scale. Previously, the scale was 0 – (vCPU x 100%).
1Some sizes support bursting to temporarily increase disk performance. Burst speeds can be maintained for up to 30 minutes at a time.
Storage capacity is shown in units of GiB or 1024^3 bytes. When you compare disks measured in GB (1000^3 bytes) to disks measured in GiB (1024^3) remember that capacity numbers given in GiB may appear smaller. For example, 1023 GiB = 1098.4 GB.
Disk throughput is measured in input/output operations per second (IOPS) and MBps where MBps = 10^6 bytes/sec.
Data disks can operate in cached or uncached modes. For cached data disk operation, the host cache mode is set to ReadOnly or ReadWrite. For uncached data disk operation, the host cache mode is set to None.
Expected network bandwidth is the maximum aggregated bandwidth allocated per VM type across all NICs, for all destinations. For more information, see Virtual machine network bandwidth
Upper limits aren't guaranteed. Limits offer guidance for selecting the right VM type for the intended application. Actual network performance will depend on several factors including network congestion, application loads, and network settings. For information on optimizing network throughput, see Optimize network throughput for Azure virtual machines.
To achieve the expected network performance on Linux or Windows, you may need to select a specific version or optimize your VM. For more information, see Bandwidth/Throughput testing (NTTTCP).
