A hybrid cloud is an infrastructure scenario that takes advantage of in-house resources as well as externally hosted resources located in the cloud. Access control and authentication are still necessary in the cloud, however; therefore, designing a cloud solution often requires duplicate resource management and deployments. With Windows Server 2012, you can extend Active Directory control into cloud-based platforms to provide hybrid cloud services through claims-based authorization.
When designing Active Directory services, you should pay attention to whether hybrid cloud services will be used and, if so, what resources and interaction will be necessary with Active Directory. You can virtualize Active Directory in Windows Server 2012 much more easily, thus enabling a domain controller to be deployed in a cloud-hosted environment.
