In the past few years, cloud computing has become one remarkable growing paradigm for offering services through the Internet on many levels. The increasing number of users requires resource provisioning strategy. Virtual machine (VM) placement is one of the keys to assure cloud consolidation and reduce power wastage. To resolve this problem, different approaches were proposed for VM placement strategies...
Energy consumption has become a significant issue for data centres. Assessing their consumption requires precise and detailed models. In the latter years, many models have been proposed, but most of them either do not consider energy consumption related to virtual machine migration or do not consider the variation of the workload on (1) the virtual machines (VM) and (2) the physical machines hosting...
Due to the popularity of cloud computing and the increase of cloud-service requests, the demand for building better cloud infrastructure is huge. However, many services that need to be provided by a cloud infrastructure are not currently available. Efficient power consumption is an example. On the other hand, the usage of some cloud services is low. But their servers keep online and working, causing...
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...
In this paper it was reviewed several existing investigations about minimization power consumption of data centers. It was suggested several approaches of task distribution in computing networks to minimize power consumption and management system for such networks.
Reducing energy consumption is part of the main concerns in cloud and HPC environments. Today servers energy consumption is far from ideal, mostly because it remains very high even with low usage state. An energy consumption proportional to the server load would bring important savings in terms of electricity consumption and then financial costs for a data enter infrastructure. In this paper, we propose...
Information and communication technology (ICT) negatively influence the environment due to production of very high CO2 emissions. One server rack produces as much emissions in one year as 25 homes. Usually, a mid-size data center contains a couple of hundred server racks. Therefore, "Green" IT and low power consumption networking infrastructures become more and more important for service...
There have been significant studies on virtual machines (VMs), including their power consumption in performing different types of tasks. The VM's power consumption with network transactions, however, has seldom been examined. This paper presents an empirical study on the power consumption of typical virtualization packages while performing network tasks. We find that both Hardware Virtualization and...
Proposals have focused on reducing energy requirements for large-scale computing facilities (LSCFs), but little research has addressed the need for energy-usage-based accounting. Energy-aware accounting and billing benefits LSCF owners and users. This article makes a case for accurate cost accounting and billing, which accounts for user-specific energy usage, and identifies the hardware- and software-level...
In this paper, we present a power/energy profiling framework for collecting and analyzing energy consumption data in compute clouds. We implement a prototype of our profiling framework and test it in a cloud computing environment. By measuring the power/ energy consumption with various combinations of system configuration and settings, we build knowledge of the extent to which each factor influences...
This paper presents a critical comparison of a virtualised data centre infrastructure and an infrastructure that consists of physical servers. Our investigation shows how virtualisation can better utilise the hardware and consequently reduce the power consumption and carbon emissions. The case study reports an extensive research phase to identify main reasons for data centre virtualisation. The data...
Virtualized infrastructure providers demand new methods to increase the accuracy of the accounting models used to charge their customers. Future data centers will be composed of many-core systems that will host a large number of virtual machines (VMs) each. While resource utilization accounting can be achieved with existing system tools, energy accounting is a complex task when per-VM granularity...
