LevCloud:使用內容定址檔案系統改善混合雲的效能

Abstract

Enterprises or organizations with existing IT infrastructure are beginning to employ a hybrid cloud model where the enterprise or organization uses its own private resources for the majority of its computing, but then bursts into the cloud when local resources are insufficient. In the paper, we propose a cluster which can dynamically offload job to cloud when local resources are insufficient. It includes a cloud resource manager integrated with distributed resource manager and a content-addressable network file system with optimization for low bandwidth and high latency network between cloud and local server. LevCloud dynamically increases or decreases cloud resources in respond to changes in demand. In our evaluation, we conducted experiments to emulate bursty and showed LevCloud reduce significant job turnaround time by dynamically leveraging cloud resources.
