Abstract

Scientific workflows have become the mainstream to conduct large-scale scientific research. In the meantime, cloud computing has emerged as an alternative computing paradigm. In this paper, we conduct an analysis of the performance of an I/O-intensive real scientific workflow on cloud environments using makespan (the turnaround time for a workflow to complete its execution) as the key performance metric. In particular, we assess the impact of varying the storage configurations on workflow performance when executing on Google Cloud and Amazon Web Services. We aim to understand the performance bottlenecks of the popular cloud-based execution environments. Experimental results show significant differences in application performance for different configurations. They also reveal that Amazon Web Services outperforms Google Cloud with equivalent application and system configurations. We then …
