Centre paper presented at 2016 IEEE conference on Cloud Computing:

Dr Anbang Ruan (Research Associate in Trusted Cloud Computing, Oxford e-Research Centre), Professor Andrew Martin (Department of Computer Science, University of Oxford), Professor David Wallom (Associate Professor and Associate Director-Innovation, Oxford e-Research Centre) and Ming Wei (Peking University) presented 'Breaking down the Monarchy: Achieving Trustworthy and Open Cloud Ecosystem Governance with Separation-of-Powers' during Session 5 of the IEEE conference: Cloud Infrastructure Management, on Wednesday 29 June.

IEEE is the world's largest professional association advancing innovation and technological excellence for the benefit of humanity. The IEEE International Conference on Cloud Computing (CLOUD) is a prime international forum for both researchers and industry practitioners to exchange the latest fundamental advances in the state of the art and practice of cloud computing, identify emerging research topics, and define the future of cloud computing.

Ruan, Martin, Wei and Wallom presented a Separation-of-Powers model which disconnects definition, enforcement and inspection from Cloud Service Providers (CSPs) in a bid to open new opportunities for achieving trustworthy and open cloud ecosystem governance.

The cloud computing ecosystem is in urgent need of effective and practical trust establishment schemes. Cloud customers currently lack approaches to effectively verify the genuine behaviours of cloud services. They can only blindly believe that the Cloud Service Providers (CSPs) are honest enough to not tamper with their data, while many others have avoided using the cloud entirely. Trust establishment schemes, such as cloud auditing and cloud attestation systems, lack controls and transparency over their trust building processes, which only blur the effectiveness of the proclaimed trustworthiness.

The authors argue that these problems ultimately result from the CSPs' autocratic governance over all the activities inside the cloud. In this paper, they present a Separation-of-Powers (SoP) model by referencing the similar concepts from the discipline of the political philosophy. Three independent roles are identified to separate the powers of definition, enforcement, and inspection from the CSPs. These roles, the paper demonstrates, form the collaborative-restrictive relationship to facilitate trustworthy cloud services and achieve the balance-of-powers.
