An Azure Tenant is a dedicated, isolated instance of the Microsoft Azure cloud platform, typically representing a single organization. It serves as the central container for managing users, groups, and subscriptions within Azure Active Directory (Azure AD). Each tenant is unique and provides a secure boundary for identity management, resource allocation, and policy enforcement. Organizations use Azure Tenants to segregate their resources, ensuring that only authorized users can access specific services and data. Tenants are essential for multi-tenant scenarios, where multiple organizations use Azure but maintain strict separation of their environments. This setup enhances security, compliance, and administrative control over cloud resources.
