Azure Role-based Access Control

In this lesson, you'll learn about Azure Role-Based Access Control (RBAC), which is a key feature to manage permissions and access to your cloud resources efficiently.

Introduction

When you have multiple IT and engineering teams working in your cloud environment, managing their access to resources can become complex. The principle of least privilege suggests granting only the necessary permissions needed to complete a task. Azure RBAC helps in managing these permissions efficiently by assigning roles to users, groups, and services.

What is Azure RBAC?

Azure RBAC allows you to control access to Azure resources through role assignments. Each role has a set of permissions that define what operations can be performed. You can use built-in roles or create custom roles based on your needs.

Key Concepts

  1. Roles : Roles define the permissions to be granted. Common built-in roles include:
    • Owner : Full access to all resources, including the right to delegate access.
    • Contributor : Create and manage all types of Azure resources but cannot grant access to others.
    • Reader : View all resources but cannot make any changes.
    • Custom roles : You can create custom roles with specific permissions tailored to your needs.
  2. Scopes : Scopes define the set of resources that the access applies to. Azure RBAC is hierarchical, meaning permissions granted at a parent scope are inherited by all child scopes. Scopes can be:
    • Management group : A collection of multiple subscriptions.
    • Subscription : All resources within an Azure subscription.
    • Resource group : A grouping of resources within a subscription.
    • Resource : A specific Azure resource, like a virtual machine or storage account.

How RBAC Works

RBAC is applied at different levels of scope to control access efficiently:

  • Management Group Level : Assigning a role at this level applies…
