SCIENTIFIC PAPERS IN CONFERENCES:

  • Effort-Based Incentives for Resource Sharing in Collaborative Volunteer Applications. Davide Vega, Roc Meseguer, Felix Freitag and Sergio Ochoa. In 17th IEEE International Conference on Computer Supported Cooperative Work in Design (CSCWD 2013).

This paper evaluates different strategies to incentivize resource sharing in colaborative and voluntary computing scenarios. The results show how such strategies can control the user reward for different types of participation. Such mecanism are expected to be part of the community cloud system in order to regulate resource sharing and encourage users to contribute.

  • Support Service for Reciprocal Computational Resource Sharing in Wireless Community Networks. Ümit Büyüksahin, Amin Khan, Felix Freitag. The 5th International Workshop on Hot Topics in Mesh Networking (IEEE HOTMESH 2013), co-located with WoWMoM 2013.

  • ElastMan: Autonomic Elasticity Manager for Cloud-Based Key-value Stores. Ahmad Al-Shishtawy, Vladimir Vlassov.  The 22nd ACM International Symposium on High-Performance Parallel and Distributed Computing (HPDC ’13).

  • ElastMan: Elasticity Manager for Elastic Key-Value Stores in the Cloud. Ahmad Al-Shishtawy, Vladimir Vlassov. The ACM Cloud and Autonomic Computing Conference (CAC 2013), Miami, FL, USA,  August 5-9, 2013. http://dx.doi.org/10.1145/2494621.2494630

The paper presents the design and evaluation of ElastMan, an elasticity controller for Cloud-based elastic key-value stores. ElastMan combines feedforward and feedback control. Feedforward control is used to respond to spikes in the workload by quickly resizing the service to meet SLOs at a minimal cost. Feedback control is used to correct modeling errors and to handle diurnal workload. ElastMan was implemented and evaluated using the Voldemort key-value store running in a Cloud environment based on OpenStack. Evaluation shows the feasibility and effectiveness of our approach to automation of Cloud service elasticity.
