On-demand Cloud Architecture for Academic Community Cloud - Another Approach to Inter-cloud Collaboration


Shigetoshi Yokoyama and Nobukazu Yoshioka

Abstract: This study describes a new approach to cloud federation architecture for academic community cloud. Two basic approaches have been proposed to deal with cloud burst, disaster recovery, business continuity, etc., in community clouds: standardization of cloud services and multi-cloud federation. The standardization approach would take time; i.e., it would not be effective until there are enough implementations and deployments following the standard specifications. The federation approach places limitations on the functionalities provided to users; they have to be the greatest common divisor of the clouds’ functions. Our approach is “cloud on demand”, which means on-demand cloud extension deployments at remote sites for inter-cloud collaborations. Because we can separate the governance of physical resources for cloud deployment and the governance of each cloud by this approach, each organization can have full control on its cloud. We describe how the problems of the previous approaches are solved by the new approach and evaluate a prototype implementation of our approach.

A New Cloud Computing Governance Framework


Ahmed Shaker Saidah and Nashwa Abdelbaki

Abstract: Nowadays, most service providers adopt Cloud Computing technology. Moving to Cloud creates new risks and challenges. The Cloud era is to outsource our services to Cloud Service Provider (CSP). However, we have to develop a strong governance framework to review the service level, to manage risk effectively and to certify that our critical information is secure. In this paper, we develop an innovative governance model. It is based on the theoretical Guo, Z., Song, M. and Song, J governance model for Cloud computing. We distribute Cloud Control Matrix (CCM) on the Guo’s model categories. This turns the theoretical Guo’s model to a practical model. Governance model alone will not allow us to bridge the gap between control requirements, technical issues and business risks. As a result, we introduce a new Cloud governance framework using the processes on the new Cloud governance model.

Cloud Governance by a Credit Model with DIRAC


Víctor Méndez Muñoz, Adrian Casajús Ramo, Ricardo Granciani Diaz and Andrei Tsaregorodtsev

Abstract: Nowadays, different eScience actors are assuming the Federated Cloud as a model for the aggregation of distributed cloud resources. In this complex environment, service delivery and resource usage is an open problem, where multiple users and communities are committed to particular policies while using federated resources. In the other hand, DIRAC has become a multi-community middleware fully interoperable in Distributed Computing Infrastructures (DCI), including several cloud managers. Furthermore, DIRAC is able to federate Infrastructure as a Service (IaaS) to provide Software as a Service (SaaS) in a transparent manner to the final user. This paper defines a credit model for the resource usage providing automatic management in federated cloud. It is presented a prototype of this model, which is implemented with DIRAC, describing a test for the model assessment and drawing up conclusions for a production level federated cloud governance.
