Natural Sciences Publishing Cor. Designing and Applying an Education IaaS System

To bring deduplication storage of VM images, this paper uses LiveDFS as the file system in image storage backend. And in order to offer stable persistent volumes to VM instances, this paper develops a distributed block-level storage system called ORTHRUS which is integrated into this IaaS system. Additionally, this paper deploys Ganglia monitoring system in the IaaS system to monitor all the physical nodes VM instances. At last, this paper designs and implements a high-performance service, a net disk service and an education management service on this IaaS system
