• Create Azure virtual machines

    There are two tiers for Azure Virtual Machines, Basic and Standard. VMs in the Basic tier are well suited for workloads that do not require load balancing or the ability to autoscale. VMs in the Standard tier support all Azure Virtual Machines configurations and features. This tier is recommended for most production scenarios.

    The Basic tier contains only a subset of the A-series VM sizes, A0–A4. The Standard tier supports all available VM sizes and series: A-Series, D-Series, Dv2-Series, F-Series, and G-Series. There are also variants of the D, Dv2, F, and G-Series sizes, called DS, DSv2, F, and GS, which support Azure Premium Storage.

     A-Series The “traditional” sizes that have been around since Azure Virtual Machines was introduced. These are your general-purpose VMs.

     D-Series Introduced in September 2014, they feature processors that are 60 percent faster than the A-Series, a higher memory-to-core ratio, and an SSD for the temporary physical disk.

     Dv2-Series Introduced in October 2015, the Dv2-Series are the next generation of the D-Series instances. They carry the same memory and disk configuration as the D-Series, yet they are on average 35 percent faster than the D-Series (thanks to the 2.4 GHz Intel® Xeon® E5-2673 v3 [Haswell] processor).

     G-Series Introduced in January 2015, the G-Series VMs are intended for your most demanding workloads. The G-Series VMs feature two times more memory and four times more storage than D-Series VMs and also include the latest Intel® Xeon® E5 v3 processors. G-Series VMs also use a SSD for the temporary physical disk.

     F-Series Introduced in June 2016, the F-Series VMs provide the same CPU performance (the same 2.4 GHz Intel® Xeon® E5-2673 v3 [Haswell] processor) as the Dv2-Series VMs but at a lower per-hour price. The difference with the F-Series is they feature 2 GB of memory per CPU core and less local SSD space. The F-Series can be an excellent choice for workloads that might not benefit from additional memory or local SSD space.

     N-Series Announced in September 2015, the N-Series VMs feature GPU capabilities, powered by NVIDIA. At the time of this writing, N-Series VMs are limited to a private preview.

    Note With the introduction of the F-Series VM sizes, Microsoft announced a new naming standard for VM sizes. Starting with the F-Series and applying to any future VM sizes, a numeric value after the family name will match the number of CPU cores. Additional capabilities, such as premium storage, will be designated by a letter following the CPU core count. For example, Standard_F8s will indicate an F-Series VM supporting premium storage with eight CPU cores (the “s” indicates premium storage support). This new naming standard will not be applied to previously introduced VM sizes.
