In this article, we will compare Azure Active Directory vs Azure AD B2C, and explore the tradeoffs involved in choosing one over the other for identity and access management. We will discuss the features and benefits of each service, as well as the challenges associated with implementing and managing them.

Azure Active Directory (Azure AD) is a cloud-based identity and access management service that helps businesses manage user identities and access to applications and resources. It provides a single sign-on (SSO) experience for users to access multiple applications with a single set of credentials.

Azure AD B2C, on the other hand, is a separate service that is designed for business-to-consumer (B2C) scenarios. It provides a comprehensive set of identity management capabilities that enable businesses to authenticate, authorize, and manage customer identities and access to applications and resources.

Identity and access management (IAM) is a critical aspect of modern businesses. It ensures that only authorized users have access to sensitive information and resources, while also ensuring that users can easily access the resources they need to perform their jobs.

Effective IAM helps businesses to reduce security risks, improve compliance, and increase productivity. It is essential for protecting sensitive data and applications, especially in the age of remote work and cloud computing.
