When ARM templates are used for the infrastructure of an application, Azure Pipelines can be used for deploying not only code but also ARM templates. Other alternatives for deploying templates in Azure include the Azure portal, Azure CLI, REST API, and Azure Cloud Shell or ARM template specs.

Whatever deployment method is used (REST API, Azure CLI, or ARM templates), it will all have a deployment mode. This can be either Incremental or Complete. In Incremental mode, all resources specified in the template will be created in Azure or their properties will be updated if the resource already exists. In Complete deployment mode, any resources that are not defined in the ARM template will be deleted. This mode does not redeploy...
