AZ-104 Exam EP 09: Azure Resource Manager

Introduction

This tutorial provides a comprehensive guide to Azure Resource Manager (ARM) as presented in the AZ-104 Exam video series. Understanding ARM is crucial for managing resources in Azure efficiently. This guide will cover key concepts, resource management strategies, and practical applications of ARM.

Step 1: Understand Azure Resource Manager

• Azure Resource Manager is the deployment and management service for Azure.
• It enables you to create, update, and delete resources in your Azure account.
• Key benefits include:
  • Centralized management of resources.
  • Ability to define resource relationships.
  • Simplified deployment through templates.

Step 2: Familiarize with Key Terminology

• Resource: A manageable item available through Azure (e.g., virtual machines, storage accounts).
• Resource Group: A container for managing and organizing related resources.
• Deployment: The process of creating resources in Azure.
• Lock: A feature that prevents accidental deletion or modification of resources.

Step 3: Manage Resource Group Deployments

• Resource groups can be created via the Azure portal, PowerShell, or CLI.

• To deploy resources:

  1. Navigate to the Azure portal.
  2. Select “Create a resource” and choose your desired resource.
  3. Specify the resource group during the creation process.

• Best practices:

  • Group related resources together for easier management.
  • Use naming conventions for clarity.

Step 4: Implement Resource Manager Locks

• Resource locks can be applied to prevent deletion or modification.

• To create a lock:

  1. Go to the resource or resource group in the Azure portal.
  2. Select “Locks” from the settings menu.
  3. Click “Add lock” and choose the lock type (Read Only or Delete).

• Tip: Use locks to safeguard critical resources from accidental changes.

Step 5: Move Resources Between Resource Groups

• Moving resources allows better organization and management.

• To move resources:

  1. Go to the resource group containing the resource.
  2. Select the resource you want to move.
  3. Click “Move” and then select “Move to another resource group.”
  4. Choose the destination resource group and confirm.

• Note: Ensure the resource is supported for moving, as some resources have restrictions.

Step 6: Remove Resources and Resource Groups

• To delete a resource:

  1. Navigate to the resource in the Azure portal.
  2. Click “Delete” and confirm the action.

• To delete a resource group:

  1. Go to the resource group.
  2. Select “Delete resource group” and confirm.

• Caution: Deleting a resource group will delete all resources contained within it.

Step 7: Understand Resource Limits

• Each Azure subscription has limits on the number of resources that can be created.
• Familiarize yourself with the specific limits for different resource types to avoid service interruptions.
• Regularly review your usage and adjust your architecture as necessary to stay within limits.

Conclusion

Azure Resource Manager is a powerful tool for managing Azure resources effectively. By understanding its core components, including resource groups, locks, and deployment practices, you can optimize your cloud infrastructure. For next steps, consider exploring Azure templates for repeatable deployments and stay updated on Azure resource limits to ensure efficient resource management.
