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.

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.

NVv2-series

Newer size recommendation: NVv3-series

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.

Note

The A8 – A11 VMs are planned for retirement on 3/2021. We strongly recommend not creating any new A8 – A11 VMs. Please migrate any existing A8 – A11 VMs to newer and powerful high-performance computing VM sizes such as H, HB, HC, HBv2 as well as general purpose compute VM sizes such as D, E, and F for better price-performance.
