Previous generations of virtual machine sizes
Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Uniform scale sets
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 Design for high performance.
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 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 VM.

- Standard_A2 is Medium
- Standard_A3 is Large
- Standard_A4 is ExtraLarge
