Entra ID and Enterprise Single Sign-On
Most of the practical benefit of choosing Azure over another cloud comes down to identity. When an internal tool, a customer portal and a mobile app all need to authenticate against the same directory an organization already manages in Entra ID, building on Azure removes a whole category of custom authentication work.
We register applications directly against the client's existing tenant, apply conditional access policies the security team has already defined, and use Entra External ID when the audience is customers rather than employees. For organizations without an existing Microsoft tenant, this advantage disappears, and the decision should rest on other factors instead.
