Now that you have finished all of the exercises in this book, we urge you to remove the VMLab resource group completely so that there aren't any lingering resources racking up Azure charges without you realizing.
So, to remove the VMLab resource group and everything in it, run the following command:
Remove-AzureRmResourceGroup -Name VMLab -force
Running this command will ensure that the entire VMLab resource group, along with everything within it, is deleted.
