Cloud computing can provide virtually unlimited scalable high performance computing resources. Cloud workflows often underlie many large scale data/computation intensive e-science applications such as earthquake modelling, weather forecasting and astrophysics. During application modelling, these sophisticated processes are redesigned as cloud workflows, and at runtime, the models are executed by employing the supercomputing and data sharing ability of the underlying cloud computing infrastructures. Temporal QOS Management in Scientific Cloud Workflow Systems focuses on real world scientific applications which often must be completed by satisfying a set of temporal constraints such as milestones and deadlines. Meanwhile, activity duration, as a measurement of system performance, often needs to be monitored and controlled. This book demonstrates how to guarantee on-time completion of most, if not all, workflow applications. Offering a comprehensive framework to support the lifecycle of time-constrained workflow applications, this book will enhance the overall performance and usability of scientific cloud workflow systems.Explains how to reduce the cost to detect and handle temporal violations while delivering high quality of service (QoS) Offers new concepts, innovative strategies and algorithms to support large-scale sophisticated驴applications in the cloud Improves the overall performance and usability of cloud workflow systemsTable of ContentsChapter 1 Introduction Chapter 2 Literature Review and Problem Analysis Chapter 3 A Scientific Cloud Workflow System Chapter 4 Novel Probabilistic Temporal Framework Chapter 5 Forecasting Scientific Cloud Workflow Activity Duration Intervals Chapter 6 Temporal Constraint Setting Chapter 7 Temporal Checkpoint Selection and Temporal Verification Chapter 8 Temporal Violation Handling Point Selection Chapter 9 Temporal Violation Handling Chapter 10 Conclusions and Contribution Bibliography Appendix: Notation Index
