Azure Resource Manager

Azure Resource Manager (ARM) 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. ARM allows you to manage your infrastructure through a declarative template.

• Resource Group Management: Organizes resources for easier management.
• Role-Based Access Control (RBAC): Provides access management for resources.
• Declarative Templates: Allows you to define your infrastructure using JSON templates.
• Tagging: Enables you to categorize resources for better tracking and billing.

Creating resources in Azure using ARM can be done via the Azure Portal, Azure CLI, or Azure PowerShell. Here is a step-by-step process to create a resource group using Azure CLI:

az group create --name MyResourceGroup --location eastus

You can also create resources using an ARM template. Here is an example ARM template to create a storage account:

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "resources": [
        {
            "type": "Microsoft.Storage/storageAccounts",
            "apiVersion": "2021-04-01",
            "name": "[parameters('storageAccountName')]",
            "location": "[parameters('location')]",
            "sku": {
                "name": "Standard_LRS"
            },
            "kind": "StorageV2",
            "properties": {}
        }
    ],
    "parameters": {
        "storageAccountName": {
            "type": "string",
            "minLength": 3,
            "maxLength": 24,
            "metadata": {
                "description": "Storage account name"
            }
        },
        "location": {
            "type": "string",
            "defaultValue": "eastus",
            "metadata": {
                "description": "Location for all resources."
            }
        }
    }
}

When using Azure Resource Manager, consider the following best practices:

• Use Resource Groups: Group related resources to manage them more effectively.
• Utilize Tags: Tag resources for better organization and cost management.
• Implement RBAC: Apply role-based access to ensure security and compliance.
• Regularly Review Resources: Periodically check resource usage and remove unnecessary items.
