Cloud System Capacity Leasing using the Open Nebula Engine

Abstract

We have shown that Open Nebula and Haizea can be used together to provide a VM management solution supporting a variety of lease types, and have presented experimental results showing how an advance reservation lease can be created by leveraging the suspend/resume capability of VMs to preempt lower-priority leases. Our results stress the importance of accurately and separately scheduling not just VM deployment over. but also runtime overhead, such as suspend/resume actions. By accurately estimating the time to perform these actions, Haizea can schedule a suspension to complete before the start of a preempting lease, avoiding performance hits resulting from overlaps in VM actions. The study of the application is thoroughly depicted in this paper.
