Current cloud data centers are fully virtualized for service consolidations and power/energy reduction. Although virtualization could reduce real time power and overall energy consumption, the energy characteristics of hypervisors hosting different workloads are not well profiled and understood. In this paper, we investigate the power and energy characteristics of mainstream hypervisors and container...
In elastic cloud computing environment, multiple virtual machines may reside in the same physical machine for services consolidation. For the same residential guest domains or multi-tiered hosting services, the inter-domain communications are complex and frequent. However, traditional inter-domain communications are conducted through the virtual network interfaces of both sending and receiving virtual...
In this paper, we study resource allocation strategy about the virtualized servers. Based on a non-cooperative game theory, we employ bidding model to solve the resource allocation problem in virtualized servers with multiple instances competing for resources. The optimal response function of utility function which we introduced makes every player bidding prices reasonable. Although utility function...
Traditional Virtual Machines are over-provisioned to provide peak performance and waste a lot of system resources. In this paper, we propose and implement a placement strategy of Virtual Machines based on workload characteristic-s. In our approach, the virtual machines are placed into various groups after several iterations and matching based on the complementary of virtual machines' workloads. Requested...
With the growth of hardware and software resources, It becomes a challenge that how to ensure the Quality of Service (QoS) of resource scheduling in multiple virtual machine system. In order to solve this problem, the authors propose a control mechanism about QoS for resource scheduling. In the control mechanism, we first propose a theoretical model. Then, we present an elicitation algorithm to resolve...
With the growth of hardware and software resources, the management of virtual machine system is becoming more and more difficult. It has become a very difficult problem that how to schedule the system resource in real time and improve the service performance of resource in a multiple virtual machine system. In order to solve this problem, the authors propose a real-time scheduling mechanism of resource...
How to meet the QoS of the applications and improve resource utilization is an important problem in virtualized environment. In this paper, we propose a utility based resource allocation policy with QoS constrained in virtualized environment. Firstly, we build a model reflecting the mapping relation between performance metrics and resource allocation through Web server benchmarking experiments. Then,...
In order to improve the resource utilization of virtual machine and control the resource allocation online effectively, in this paper, we present a grey prediction control model used for dynamic resource allocation in virtual machine as workloads changing. First, we forecast the allocation of virtualized resources by the grey control model. We also adjust the boundary conditions of grey prediction...
In this paper we present results from test and quantitative analysis of leading hypervisors Xen, Kvm and Vmware. Our test comparison was carried out using benchmarks which can performance on the overall performance, performance isolation, and scalability of virtual machines running on these three hypervisors. To compare, we need to measure the efficiency of the virtualization technologies. We define...
Virtual machines with advances in software and architectural support have emerged as the basis for enterprises to allocate resources recently. One main benefit of virtual machine is server consolidation. However, flexible and complex consolidation results in some unpredictable performance problems and introduces new requirements, such as proper configurations for scheduler and reasonable arrangements...
