Define Azure AD B2C vs B2B uses and differences
Could you please define cloud based authentication services Azure AD B2C and B2B with it's uses and their differences if any. Please provide list of web resources if you can.
Answer
The uses of Azure AD B2C (Business to Consumer) and Azure AD B2B (Business to Business) are very different. These differences are highlighted in the documentation.
B2C documentation: https://azure.microsoft.com/en-in/services/active-directory-b2c/
Azure Active Directory B2C is a highly available, global, identity management service for consumer-facing applications that scales to hundreds of millions of identities.
In a nutshell, it allows you to authenticate customers using social identities, like Facebook or Microsoft Account, but still within the context of Azure AD.
B2B documentation: https://azure.microsoft.com/en-in/documentation/articles/active-directory-b2b-collaboration-overview/
Azure AD B2B collaboration lets you enable access to your corporate applications from partner-managed identities. You can create cross-company relationships by inviting and authorizing users from partner companies to access your resources.
In a nutshell, it allows you to authenticate corporate users from other companies.
So one is for consumer-facing applications, and one is for business applications.
