Designing Contextualized Workflows in the Cloud

Cloud workflow allows automating the workflow procedure through a compilation of known sequences of actions in the cloud environment. There is a notable absence of a holistic view in current cloud workflow systems that, on one hand, to capture the evolving context when designing workflow models, and on the other hand, to help a specific user interact with the system during QoS prediction and dynamic selection of the relevant cloud services. In this paper we firstly review recent works on designing cloud workflows by discussing the opportunities and challenges respectively. We then propose a contextualized approach and research directions to improve the design process of cloud workflows in a user-oriented paradigm. The contextualized methodology could be considered as an alternative attempt to address the socio-technical issues in designing cloud workflows.
