Azure Active Directory (Azure AD)

Overview

• Azure AD: A multi-tenant, cloud-based identity and access management solution for resources in the cloud.
• Purpose: Manages user identities, authenticates users, and assigns permissions to resources in Azure.
• Benefits:
  • Reduces developer programming efforts by handling user management infrastructure.
  • Provides Single Sign-On (SSO) capabilities.
  • Offers affordable and easy-to-use solutions for IT admins.
  • Scalable and highly available with multiple data centers to ensure reliability.

Key Features

• Creating Users, Groups, and Devices: Essential for managing identities and access in Azure.
• Role-Based Security: Implement role-based access controls to streamline IT processes and improve security.
• Guest Users: Ability to add users from outside the organization with Microsoft accounts.
• Multiple Directories: Use multiple directories for different environments (e.g., testing, production).

Single Sign-On (SSO)

• SSO Feature: Allows users to log in once and gain access to multiple applications without re-entering credentials.
• Applications: Supports thousands of cloud SaaS applications.
• SSO Benefits:
  • Enhances productivity by eliminating repeated logins.
  • Simplifies administration for IT personnel.

Integration with On-Premise Directories

• AD Connect: Synchronizes on-premise Active Directory with Azure AD for unified identity management.
• Synchronizing Users: Importance of syncing on-premise users to allow access to both local and Azure applications.
• Federation: Enables users to authenticate to both on-premise and Azure applications seamlessly.
