Xuezhi Chai, Cao Jian · Journal of Chinese Computer Systems · 2012
Along with the development of Cloud Computing,improving OoS(Quality of Service) as well as reducing OC(Operation Cost) is increasingly becoming an urgent goal.Cloud-oriented workflow technology is now regarded as a pretty good solution: For users of could computing,cloud workflow enables a complex application instance to be Abstractly defined,flexibly configured and auto-operated;for enterprises who provide cloud services,cloud workflow brings them auto-scheduling of tasks,optimization and management of computing resource.This paper proposed a short introduction to the technology of both workflow and Cloud Computing;Introduced the background in which Cloud Workflow generated;Meanwhile,the following part fully compared Cloud Workflow with other workflows(Business Workflow and Grid Workflow) according to the technical characteristics of workflow;After that,4 instances of Cloud Workflow management system are listed,as well as their similarities and differences.At the end of this paper,a summary,and predicted the possible trend of Cloud Workflow in the future are given.
