 Create a VM configuration with [New-AzVMConfig](/powershell/module/az.compute/new-azvmconfig), then create the VM with [New-AzVM](/powershell/module/az.compute/new-azvm). The following example creates a VM that serves as a web server. The `-AsJob` option creates the VM in the background, so you can continue to the next step:

 The virtual machine takes a few minutes to create. Don't continue with the next step until Azure finishes creating the VM.
