Cost-based prevention of violations of service level agreements in composed services using self-adaptation

Philipp Leitner, Schahram Dustdar, Branimir Wetzstein, Frank Leymann
2012 2012 First International Workshop on European Software Services and Systems Research - Results and Challenges (S-Cube)  
At its core, PREvent is a self-optimizing system in the sense of autonomic computing, with the target of minimizing the total costs of adaptations and SLA violations for the service provider.  ...  In this work, a framework for optimizing adaptations of service compositions with regards to SLA violations has been developed.  ...  For each composition instance with predicted violations, this component needs to find the subset of adaptations that minimizes the predicted total costs (T C) for the service provider.  ...

Synthesizing Cost-Minimal Partners for Services [chapter]

Jan Sürmeli, Marvin Triebel
2013 Lecture Notes in Computer Science  
We synthesize a cost-minimal partner for a given service based on additional behaviorial constraints.  ...  Adapter synthesis bridges incompatibilites between loosely coupled, stateful services. Formally, adapter synthesis reduces to partner synthesis.  ...  In the setting of adaptation, a cost-minimal adapter may reduce the adaptation costs, the costs of each adapted service, or overall costs.  ...

A Cost-Based Adaptive Handover Hysteresis Scheme to Minimize the Handover Failure Rate in 3GPP LTE System

Doo-Won Lee, Gye-Tae Gil, Dong-Hoi Kim
2010 EURASIP Journal on Wireless Communications and Networking  
We deal with a cost-based adaptive handover hysteresis scheme for the horizontal handover decision strategies, as one of the selfoptimization techniques that can minimize the handover failure rate (HFR  ...  Especially, for real-time operation, we propose an adaptive hysteresis scheme with a simplified cost function considering some dominant factors closely related to HFR performance such as the load difference  ...  Therefore, in this paper, since the cost function is necessitated for a new adaptive handover hysteresis scheme with aim for minimizing the HFR in 3GPP LTE system, we apply the cost function of the vertical  ...

Novel Sensing Approach for Predicting SLA Violations
English

Vidya Rajasekaran, A.Asha Ashok, R Manjula
2014 International Journal of Computer Trends and Technology  
Service providers carry out adaptation measures in the case of violations. Adaptation is considered as an instant deed (i.e.) for each Composition instance separately.  ...  To achieve the highest score the service provider should provide services with minimum cost and maximum efficiency and quality.  ...  If adaptation is only on cost, quality will get reduced for the service during adaptations.  ...

Cost-aware live migration of services in the cloud

David Breitgand, Gilad Kutiel, Danny Raz
2010 Proceedings of the 3rd Annual Haifa Experimental Systems Conference on - SYSTOR '10  
We observe that there is a non-trivial trade-off between minimizing the copy phase duration and maintaining an acceptable quality of service during the pre-copy phase, and introduce a new model to quantify  ...  Finally, we simulate, using real traces, live migrations of a virtual machine running a web server and compare the migration cost using our algorithm and commonly used livemigration methods.  ...  Theorem 1 If the dirtying probability is uniform and independent, then the CALM-adaptive algorithm achieves the minimal possible cost for the migration.  ...
