Temporary Vm by Arm Template_1

Creat a VM with misc resources by ARM Template

To create a smiple VM to be accessable, we need to create a resource group, a virtual network, a subnet, a public IP, and a VM.

Problems and ToDoList to improve

To access it, we need to get it’s public IP address from Azure Web Console. It would be better to assign a DNS name to it.
Using a prameter file to store the password and other parameters instead of using command line.
The password is in plain text in the command line. It would be better to use a key pair.
