Azure Resource Manager is the deployment and management service for Azure. It provides a management layer that enables you to create, update, and delete resources in your Azure account (CUD)
When a user sends a request from any of the Azure tools, APIs, or SDKs, Resource Manager receives the request.
It authenticates and authorizes the request. Resource Manager sends the request to the Azure service, which takes the requested action. Because all requests are handled through the same API, you see consistent results and capabilities in all the different tools.
ARM template – A JavaScript Object Notation (JSON) file that defines one or more resources to deploy to a
resource group, subscription, management group, or tenant. The template can be used to deploy the
resources consistently and repeatedly. See Template deployment overview.
When you deploy a template, Resource Manager converts the template into REST API operations
