Two Research Contributions at the CCGrid 2017 Conference

Two RestAssured research contributions were presented at this year’s CCGrid conference in Madrid. CCGrid, the IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing, serves as the major international forum for presenting and sharing recent research results and technological developments in the fields of Cluster, Cloud and Grid computing and had this year its 17th installment (


The first research contribution entitled “Optimized cloud deployment of multi-tenant software considering data protection concerns,” authored by Dr. Zoltan Mann and Dr. Andreas Metzger from paluno (The Ruhr Institute for Software Technology) of the University of Duisburg-Essen, addresses the question of how secure hardware enclaves as part of cloud servers may increase the optimization possibilities of cloud providers. New algorithms are proposed to take advantage of such capabilities with the aim of ensuring data protection and minimizing costs simultaneously. Experimental results suggest that even a small percentage of secure hardware enclaves may lead to significant cost savings.


The second research contribution entitled “Joint optimization of scaling and placement of virtual network services” was joint work of Dr. Zoltan Mann with researchers from the University of Paderborn. It describes a new method and new algorithms for adaptively scaling and placing virtualized network functions (e.g., firewall, deep packet inspection, anti-virus, parental control) and their data flows in the cloud.
