Proceedings ArticleDOI
Performance Modeling and Prediction of Parallel and Distributed Computing Systems: A Survey of the State of the Art
TL;DR: A wide range of the performance modeling approaches that spans from the high-level mathematical modeling to the detailed instruction-level simulation are described, estimating the model development and evaluation effort, the efficiency, and the accuracy.
Proceedings ArticleDOI
Coordinating CPU and Memory Elasticity Controllers to Meet Service Response Time Constraints
TL;DR: The design of an autonomic resource controller using a fuzzy control approach as a coordination technique that dynamically adjusts the right amount of CPU and memory required to meet the performance objective of an application, namely its response time.
Proceedings ArticleDOI
Self-Adaptive and Resource-Efficient SLA Enactment for Cloud Computing Infrastructures
TL;DR: This paper proposes self-adaptive rule-based knowledge management for autonomic VM reconfiguration considering the rapidness of changes in the workload, i.e., WV, and introduces a novel WV categorization and present cost and volatility based methods for self-tuning.
Journal ArticleDOI
A hybrid cloud controller for vertical memory elasticity
TL;DR: A novel hybrid elasticity approach that takes into account both the application performance and the resource utilization to leverage the benefits of both approaches is proposed and a feedback controller for vertically scale the memory of cloud applications is proposed.
Proceedings ArticleDOI
Autonomic SLA-Aware Service Virtualization for Distributed Systems
TL;DR: An SLA-aware Service Virtualization architecture that provides non-functional guarantees in the form of Service Level Agreements and consists of a three-layered infrastructure including agreement negotiation, service brokering and on demand deployment is introduced.
