Azure Active Directory (Azure AD) is a cloud-based identity and access management service from Microsoft. It helps organizations manage user identities and access to resources, enabling secure sign-ins and access to applications. Azure AD is essential for managing users, assigning licenses, and integrating with services like Microsoft Teams.

To create and manage users in Azure AD, you can navigate to the Azure portal, where you can add new users, assign licenses, and configure user settings. The process is straightforward and allows for efficient user management, ensuring that each user has the appropriate access to resources.

Role-Based Access Control (RBAC) is a method for regulating access to resources based on the roles of individual users within an organization. In Azure AD, RBAC allows you to provide users with just enough administrator permissions to perform their tasks. You can enhance RBAC's functionality using Azure Privileged Identity Management (PIM), which helps manage and control access to sensitive resources more effectively.
