Delete an azure VM using PowerShell

See the headline estimate a lot of people will think this thing also want to write a blog, can be more water point

hahaha, of course not so simple, but not too difficult, this time to introduce is really how to delete the virtual machine in Azure, the removal of the virtual machine itself is a simple and easy task

It is absolutely true that the mouse click on the portal is not deleted. But because Azure compute and storage is detached, deleting a virtual machine actually simply removes the compute power of azure, itself Azure OS disk, data disk, Nic These are also retained in the azure environment

The benefits of doing this are obvious and can prevent your data from being lost due to VM deletion, and it is also recommended to keep the disk after the production environment deletes the VM, waiting for the confirmation data to be deleted before removing the disk from the storage account or the managed disk.

However, sometimes we are very clear to the VM and related information completely removed, but the normal removal of the VM process we need to manually delete the VM, and then delete the disk, delete the network card, public IP and so on these need to be done manually, however, many times the user does not actually have this habit

Many users also do not know how to delete these legacy resources, often think that the removal of VMS is all right, the result is often the azure environment will be left a very large number of disks, network cards, public IP and other resources, on the one hand, resulting in additional costs, on the other hand also makes the azure environment look messy

The script you share today can help you avoid this problem, it's very simple

1. Deleting VMS

2. Remove the NIC associated with the VM

3. Remove the public IP associated with the NIC

4. Delete the OS disk associated with the VM

5. Delete the data disks associated with the VM

It is important to note that currently only support the unmanaged disk, but also note that the data disk these scripts will be all deleted, so before running to be careful, please make sure that the VM related things you do not need to run the script!!
