Previous generations of virtual machine sizes

This section provides information on previous generations of virtual machine sizes. These sizes can still be used, but there are newer generations available.

F-series

F-series is based on the 2.4 GHz Intel Xeon® E5-2673 v3 (Haswell) processor, which can achieve clock speeds as high as 3.1 GHz with the Intel Turbo Boost Technology 2.0. This is the same CPU performance as the Dv2-series of VMs.

F-series VMs are an excellent choice for workloads that demand faster CPUs but do not need as much memory or temporary storage per vCPU. Workloads such as analytics, gaming servers, web servers, and batch processing will benefit from the value of the F-series.

MBps = 10^6 bytes per second, and GiB = 1024^3 bytes.

1 The maximum disk throughput (IOPS or MBps) possible with a Fs series VM may be limited by the number, size, and striping of the attached disk(s). For details, see Designing for high performance.

Ls-series

The Ls-series offers up to 32 vCPUs, using the Intel® Xeon® processor E5 v3 family. The Ls-series gets the same CPU performance as the G/GS-Series and comes with 8 GiB of memory per vCPU.

The Ls-series does not support the creation of a local cache to increase the IOPS achievable by durable data disks. The high throughput and IOPS of the local disk makes Ls-series VMs ideal for NoSQL stores such as Apache Cassandra and MongoDB which replicate data across multiple VMs to achieve persistence in the event of the failure of a single VM.

NVv2-series (Preview)

Newer size recommendation: NVv3-series (Preview)

The NVv2-series virtual machines are powered by NVIDIA Tesla M60 GPUs and NVIDIA GRID technology with Intel Broadwell CPUs. These virtual machines are targeted for GPU accelerated graphics applications and virtual desktops where customers want to visualize their data, simulate results to view, work on CAD, or render and stream content. Additionally, these virtual machines can run single precision workloads such as encoding and rendering. NVv2 virtual machines support Premium Storage and come with twice the system memory (RAM) when compared with its predecessor NV-series.

Each GPU in NVv2 instances comes with a GRID license. This license gives you the flexibility to use an NV instance as a virtual workstation for a single user, or 25 concurrent users can connect to the VM for a virtual application scenario.

Standard A0 - A4 using CLI and PowerShell

In the classic deployment model, some VM size names are slightly different in CLI and PowerShell:

  • Standard_A0 is ExtraSmall
  • Standard_A1 is Small
  • Standard_A2 is Medium
  • Standard_A3 is Large
  • Standard_A4 is ExtraLarge

Size table definitions

  • Storage capacity is shown in units of GiB or 1024^3 bytes. When comparing 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.
  • If you want to get the best performance for your VMs, you should limit the number of data disks to 2 disks per vCPU.
  • Expected network bandwidth is the maximum aggregated bandwidth allocated per VM type across all NICs, for all destinations. Upper limits are not guaranteed, but are intended to provide guidance for selecting the right VM type for the intended application. Actual network performance will depend on a variety of factors including network congestion, application loads, and network settings. For information on optimizing network throughput, see Optimizing network throughput for Windows and Linux. To achieve the expected network performance on Linux or Windows, it may be necessary to select a specific version or optimize your VM. For more information, see How to reliably test for virtual machine throughput.

Older generations of virtual machine sizes

This section provides information on older generations of virtual machine sizes. These sizes are still supported but will not receive additional capacity. There are newer or alternative sizes that are generally available. Please refer to Sizes for Windows virtual machines in Azure or Sizes for Linux virtual machines in Azure to choose the VM sizes that will best fit your need.

For more information on resizing a Linux VM, see Resize a Linux virtual machine using Azure CLI. If you're using Windows VMs and prefer to use PowerShell, see Resize a Windows VM.
