Scientific Workflow Scheduling with Provenance Support in Multisite Cloud

Recently, some Scienti c Workflow Management Systems
(SWfMSs) with provenance support (e.g. Chiron) have been deployed
in the cloud. However, they typically use a single cloud site. In this
paper, we consider a multisite cloud, where the data and computing
resources are distributed at di fferent sites (possibly in di fferent regions).
Based on a multisite architecture of SWfMS, i.e. multisite Chiron, we
propose a multisite task scheduling algorithm that considers the time
to generate provenance data. We performed an experimental evaluation
of our algorithm using Microsoft Azure multisite cloud and two real-life
scienti c workflows, i.e. Buzz and Montage. The results show that our
scheduling algorithm is up to 49:6% better than baseline algorithms in
terms of execution time
