Temporal QOS Management in Scientific Cloud Workflow Systems

Preface

Cloud computing is the latest market-oriented computing paradigm which can provide virtually unlimited scalable high-performance computing resources. As a type of high-level middleware services for cloud computing, cloud workflow systems are a research frontier for both cloud computing and workflow technologies. Cloud workflows often underlie many large-scale data/computation-intensive e-science applications such as earthquake modelling, weather forecast and astrophysics. At the build-time modelling stage, these sophisticated processes are modelled or redesigned as cloud workflow specifications which normally contain the functional requirements for a large number of workflow activities and their non-functional requirements such as Quality ...
