USING ARM TEMPLATE TO DEPLOY A VIRTUAL MACHINE

WHAT ARE ARM TEMPLATES?
ARM stands for Azure Resource Manager, which is Microsoft’s deployment and management service for Azure. You use the ARM management layer for creating, updating, and deleting Azure resources. ARM templates are a form of infrastructure as code, a concept where you define the infrastructure you need to be deployed. You no longer need to click around the portal creating virtual machines or writing scripts to deploy a storage account. Instead, the template defines the resources, and the Azure ARM management layer is responsible for creating the infrastructure.
