When you create an azure virtual machine, there are two types of virtual machines: basic and standard.

The basic types of virtual machines have the following characteristics:

1. Reduced functionality: Basic types of virtual machines do not include load balancing and auto-scaling capabilities

2. Single-instance applications, such as: development with virtual machines, test servers, etc., without SLA

3. The price is cheaper than the standard type of virtual confidential.


Microsoft Azure offers different sizes of computing power, and the types of virtual machines currently supported by Microsoft Azure are the A-series and D-series.

the types of a-series virtual machines are as follows:

In addition to the A0 virtual machine type, its CPU is shared with other users. Other types of virtual machines, such as A1-a7, whose CPUs are exclusive, are not shared with other users.


the types of D-series virtual machines are as follows:

The benefits of the Azure Virtual Machine,d series for a series are:

1. Single VM more CPU Core

D-Series virtual machines have a maximum configuration of 16CORE/112GB ram compared to the configuration of maximum 8CORE/56GB RAM for a-series single VM


2. D-Series CPU performance increased by about 60% compared to a series

The D-series VMs are designed to run applications that require higher computing power and temporary disk performance. D-Series VMS provide faster processors, higher memory core ratios, and solid state drives (SSDs) for temporary disks.


3. Added local temporary SSD storage

Note that this is a temporary storage, which is displayed as D in Windows, and is/DEV/SDB1 on Linux systems.

Pros: High ioPS; Disadvantages: Non-persistent storage, files are at risk of loss and cannot retain important files.


4. A larger local temporary disk

As shown in the table above, the local temporary disk is 800G maximum.

Whether it's a-series VM or a D-series VM. Local persistent disks are SAS disks with IOPS of 500 per disk.


if we have higher performance requirements for disks, we can use the Cpu/ram configuration of the DS series Vm,ds series virtual machines with the D-series virtual machines in the same place, except that the DS-series VMs are on-premises persistent disks that are SSDS and can provide higher disk IOPS performance.

There is also a new type of VM, known as G-series VM

will provide more memory and more local solid state drive (SSD) storage than the current VM size. The largest G-series will provide 448 GB of RAM and 6.5 TB of local SSD storage.

Azure Premium Storage is a new type of SSD-based storage designed to support I/O intensive workloads.
