Scientific Workflow Management System for Clouds

Abstract

Infrastructure-as-a-Service clouds offer access to a scalable virtualized infrastructure on a pay-per-use basis. This is greatly beneficial for the deployment of scientific workflows, and as a result considerable effort is being made to develop and update existing workflow management systems to support the cloud resource model. The majority of existing systems are designed to work with traditional distributed platforms such as grids and clusters in which the resources are limited and readily-available. In contrast, clouds offer access to elastic and abundant resources that can be provisioned and deprovisioned on-demand. In this chapter, we present our efforts to extend an existing workflow s..
