Implementation of Cloud Infrastructure Monitor Platform with Power Saving Method

With the popularity of cloud computing due to increasing requests for cloud services, the demand for building better cloud infrastructure is increasing. Many services on cloud infrastructure are not being accessed all the time, during periods of low usage, if lots of servers keep working, it will cause unnecessary power waste. The aim of this paper is based on the Cloud service Infrastructure as a Service, use KVM and libvirt to build cloud environments. By giving every host and VM a power cap, we perform live-migration on VMs and shutdown idle hosts to save power. We also build an interface that enables users to monitor virtual machines and physical machines. In the experiment, we use PDU to record the power consumption information, and from analysis of these data we prove that we can more effectively utilize hardware resources and save power.
