Research And Application Of VM Consolidation Based On OpenStack Cloud

In recent years, the emergence of cloud computing has changed the traditional data center’s operational way. Due to the excellent performance and frequent social concern in all aspects, some manufacturers have increased the investment in cloud computing, such as Amazon, IBM, began to design, development and deployment of cloud solutions to optimize their own data center, improve market share. Some open-source solutions are also underway, such as Eucalyptus and OpenStack. Cloud architectures exploit virtualization techniques to provision multiple Virtual Machines(VMs) on the same physical host, so as to efficiently use available resources, for instance, to consolidate VMs in the minimal number of physical servers to reduce the runtime power consumption. VM consolidation has to carefully consider the aggregated resource consumption of co-located VMs, in order to avoid performance reductions and Service Level Agreement(SLA) violations. While various works have already treated the VM consolidation problem from a theoretical perspective, this paper focuses on it from a more practical viewpoint, with specific attention on the consolidation aspects related to power, CPU, and networking resource sharing. Moreover, In addition, this paper puts forward some suggestions to improve the architecture design of the open source cloud infrastructure management platform along three main dimensions, namely power consumption, host resources, and networking. Through the design of the experiment, we can prove that the real time migration of virtual machine should take full account of the interference between cooperative virtual machine, which is easy to explain in theory, but in the past research it is not effective to detect the impact value,and this is one of the innovations of this paper.
