Introduction ARM templates follow the Desired State Configuration (DSC) pattern. This means that the ARM template describes what the desired Azure infrastructure should look like. When an ARM template is applied to an Azure environment, the differences between the template and the current state are calculated and applied. The end result is an environment that conforms to the ARM template.
While this is true for many of the Azure resources, it may not always be true for properties of ARM resources.
