I have been using various user management systems for a long time, and when I had to work with cloud solutions, I chose Microsoft Active Directory (AD) and Azure Active Directory (Azure AD). These platforms have significantly improved access management and security in my organization. Active Directory is a classic solution for managing users in an on-premises network. It provides powerful tools for authentication, authorization, and resource management in a corporate environment. But when our organization began to move to the cloud, we faced the need to integrate with Azure AD. Azure AD is a cloud version of Active Directory that allows you to securely manage access to cloud and hybrid applications. Thanks to Azure AD, I can set up a single point of access for all the services used in our company, be it Office 365 or third-party applications.
