Traditional researches on scheduling of cloud workflow applications were mainly focused on time and cost. However, security and reliability have become the key factors of cloud workflow scheduling. Taking time, cost, security and reliability into account, we present a trust-based scheduling strategy.We firstly formulate the cloud workflow scheduling and then propose the corresponding algorithm,...

The paper firstly analyzes the characteristic of existing workflow applications and proposes cloud workflow layered model and design method based on the current major cloud computing trends. Considering the features on the cloud workflow system in distributed heterogeneous environment, the paper proposes a brief introduction to approach to cloud workflow system. Next, three deployment models of...

Cloud computing is a promising solution to provide the resource scalability dynamically. In order to support large scale workflow applications, we present Nuts-LSWAP which is implementation for Cloud workflow. Then, a novel Min-cost with delay scheduling algorithm is presented in this paper. We also focuses on the global scheduling including genetic evolution method and other scheduling methods...

During the past several years, the grid application executed same jobs on one or more hosts in parallel, but the recent grid application is requested to execute different jobs linearly. That is, the grid application takes the form of workflow application. In general, efficient scheduling of workflow applications is based on heuristic scheduling method. The heuristic considering relation between...

Workflow scheduling plays a vital role in advanced manufacturing, and it deserves research efforts to warrant further improvement. This paper proposes an intelligent workflow scheduling system (iWFSS) to integrate information, processes, and knowledge into a unified framework that provides a total solution to online scheduling. The iWFSS consists of an information system, a workflow system, and...

Cloud Computing offers wide computation and resource facilities for execution of various application workflows. Many different resources involved in execution of single workflow. Cloud Computing offers highly dynamic environment in which the system load and status of resource changes frequently. As the workload increases with increase in Cloud Services and clients there is a need to handle thes...
