As businesses continue to expand, the need for secure and efficient identity management becomes increasingly important. Active Directory (AD) has been a popular solution for managing identities and access within organizations for many years. However, with the rise of cloud computing, Microsoft developed Azure Active Directory (Azure AD) as a cloud-based identity and access management solution. In this article , we will explore the differences between on-premise Active Directory and Azure Active Directory.
What is Active Directory?
Active Directory is a Microsoft technology that provides a centralized directory service for managing identities and access to resources within an organization’s network. It allows administrators to manage user accounts, computers, groups, and other resources. The primary purpose of Active Directory is to authenticate and authorize users and computers to access resources within the organization’s network.
