Talk:

 

Accountability is a principle well suited to overcome trust concerns when operating sensitive business applications over the cloud. We argue that accountability builds upon transparency and control, and investigate in control of services in service-oriented architectures. Control needs to reach out to different layers of a SOA, both horizontally and vertically.
 
We introduce an aspect model for services that enables control on these layers by invasive modification of platform components and upon service orchestration. This is seen as a major constituent of an accountability framework for the cloud, which is the objective of an upcoming collaborative research project.
