Sevil Dräxler, Holger Karl, Zoltán Ádám Mann: Joint Optimization of Scaling and Placement of Virtual Network Services. In: IEEE/ACM 17th International Symposium on Cluster, Cloud and Grid Computing, CCGrid 2017, Madrid, Spain, 2017, IEEE Computer Society, 2017.
This publication 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.

This publication 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.
Zoltán Ádám Mann: Two are better than one: An algorithm portfolio approach to cloud resource management. In: Proceedings of the 6th European Conference on Service-Oriented and Cloud Computing (ESOCC 2017), Springer LNCS vol. 10465, pp. 93-108, 2017.
This paper suggests an algorithm portfolio approach in which multiple algorithms for dynamic optimization of resource allocation in virtualized data centers coexist. Based on continual monitoring and analysis of the state of the data center, the optimization algorithm that is most suitable is chosen on the fly. Thereby, the balance between optimization quality and reaction time can be tuned adaptively. Empirical results show that this approach leads to improved overall results.
