I use IDCS to support other cloud services including the Oracle API Platform, Digital Assistant, and Content Cloud. I also use the product as an OAuth 2.0 provider for custom applications including protecting runtime APIs and JET applications. We have also implemented the OIM Connector for synchronization of on-premise identities with the cloud.

We use the Oracle Identity Cloud Service because our customers mostly run Oracle applications, so it's the best solution. Now we are integrating it with Azure Active Directory and enhancing our applications with a hybrid cloud methodology. Our clients can use our Azure Active Directory with the Oracle Identity Cloud Service. 

I used it for user provisioning, role-based access control, and single sign-on. I had various different use cases. 

The primary use case is for identity management only.

The primary use case for this solution is user provisioning.
