Cloud-scale automation requires significant changes in the operation of a data center. Depending on the usage pattern of the cloud, either cloud provider or cloud consumer, the impact to your data center differs.

This talk will describe an architectural view on all aspects of SDE and how it addresses the requirements triggered by cloud environments.
