It is a framework for enabling convenient, on-demand network access to a shared pool of computing resources. Load balancing is one of the main challenges in cloud computing which is required to distribute the dynamic workload across multiple nodes to ensure that no single node is overwhelmed. It helps in optimal utilization of resources and hence in enhancing the performance of the system. The goal of load balancing is to minimize the resource consumption which will further reduce energy consumption and carbon emission rate that is the dire need of cloud computing. This determines the need of new metrics, energy consumption and carbon emission for energy-efficient load balancing in cloud computing. This paper discusses the existing load balancing techniques in cloud computing and further compares them based on various parameters like performance, scalability, associated overhead etc. that are considered in different techniques. It further discusses these techniques from energy consumption and carbon emission perspective. Keywords: Cloud computing, Load balancing, Energy efficiency...

Load balancing is one of the main challenges in cloud computing which is required to distribute the dynamic workload across multiple nodes to ensure that no single node is overwhelmed. existing Load Balancing techniques that have been studied, mainly focus on reducing overhead, service response time and improving performance etc., but none of the techniques has considered the energy consumption and carbon emission factors. Therefore, there is a need to develop an Energy-efficient load balancing technique that can improve the performance of cloud computing along with maximum resource utilization, in turn reducing energy consumption. Green Computing in Clouds Green Computing is the practice of implementing policies and procedures that improve the efficiency of computing resources in such a way as to reduce the...

Virtual Desktop Infrastructure (VDI) Definition - What does Virtual Desktop Infrastructure (VDI) mean? Virtual desktop infrastructure (VDI) is a virtualization technique enabling access to a virtualized desktop, which is hosted on a remote service over the Internet. It refers to the software, hardware and other resources required for the virtualization of a standard desktop system. VDI is also known as a virtual desktop interface. Techopedia explains Virtual Desktop Infrastructure (VDI) VDI is a shadow copy of the desktop including its OS, installed applications and documents, which are stored and executed entirely from the server hosting it. VDI provides users the ability to access their desktop remotely, often even from a handheld device because the entire process of executing the interface is done at the central server. VDI operates by storing OS preferences, software...

...GREEN CLOUD COMPUTING ABSTRACT: Cloud computing is a highly scalable and cost-effective infrastructure for running HPC, enterprise and Web applications. However, the growing demand of Cloud infrastructure has drastically increased the energy consumption of data centers, which has become a critical issue. High energy consumption not only translates to high operational cost, which reduces the profit margin of Cloud providers, but also leads to high carbon emissions which is not environmentally friendly. Hence, energy-efficient solutions are required to minimize the impact of Cloud computing on the environment. In order to design such solutions, deep analysis of Cloud is required with respect to their power efficiency. Thus, in this chapter, I discuss various elements of Clouds which contribute to the total energy consumption and how it is addressed in the literature. I also discuss the implication of these solutions for future research directions to enable green Cloud computing. The paper also explains the role of Cloud users in achieving this goal.

...Cloud computing is a new area of research currently being studied [1]. Basically it’s not a technology it’s a computing model. We can also define Cloud computing as both the applications delivered as services over the internet and the hardware and system software in the data centers that provide those services [2]. OR type of parallel and distributed system consisting of a collection of interconnected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources [3].Cloud computing purely relies on the fact that sharing computing resources rather to have applications on local servers or devices if resources are not equally distributed then this will result in resource wastage. The cloud computing platform guarantees subscribers that it sticks to the service level agreement (SLA) by providing resources as service and by needs based on the broker policy[4]. So in order to get maximum benefit from cloud computing there is need to dynamically balance the load among servers and improve utilization of resources. There are still some areas that are needed to be focused on in cloud computing. Resource Management Task Scheduling The task scheduling goals of Cloud computing is provide optimal tasks scheduling for users, and provide the entire cloud system throughput and QoS at the same time. Scheduling is the process of allocating tasks to available resources on the basis of tasks need [5].The main purpose for scheduling is to...

I understand that failure to attribute material which is obtained from another source may be considered as plagiarism. (Signature of student) Abstract Cloud computing is a breakthrough innovation in information technology industry. It brings new efficiencies and advantages to business. There is much hype about environmental impacts of cloud computing on green issues. Some favour of cloud computing as solution to green issues while others blame cloud computing as burden to environmental problems. Cloud computing, nevertheless, like other technology, is neutral. It can be either cause or solution to environmental issues. There is growing pressure on cloud computing industry to reduce the environmental impacts of their data centres. The current trend focuses on developing green cloud computing. However, the evaluation of solutions to green cloud computing bases on certain standards, metrics and benchmarks, which assess only parts of the environmental issues with cloud computing. This report will concentrate on green issues with cloud computing. Significant positive and negative impacts of cloud computing on the environment issues will be investigated. Next, a classification of green issues with cloud computing also...

Nevertheless, investment in largescale Solar Power Generators (SPGs) is largely impeded by the intermittent nature of solar power. Since the electricity market has a critical responsibility to maintain the reliability of energy supply, the SPG can be registered only as the market semi-scheduled generator (AEMC, 2011). This option excludes the advantages of providing baseload supply, which in turn impedes efficient market contracting for SPGs...

...How Geoengineering Works: 5 Big Plans to Stop Global Warming At first blush, geoengineering sounds like outrageous junk science. Surely there's an easier solution to the problem of global warming than technologically altering Earth's atmosphere, its cloud formations and even outer space. But when compared with the alternativedrastically reducing the amount of carbon dioxide blanketing the planet by changing the behavior of billions of people and thousands of industries, not to mention slow-moving governmentssome scientists are beginning to take the seemingly outrageous schemes a lot more seriously. Here are the mechanics behind five plans to jury-rig the Earth. 1. Copy a Volcano (Photograph by Tarko Sudiarno/AFP/Getty Images) A volcanic eruption can bellow many million tons of sulfur-dioxide gas into the atmosphere, creating a cloud that blocks some of the sun's radiation. By injecting the atmosphere with sulfur, some scientists believe they could likewise block solar radiation and potentially cool the planet. Sulfur dioxide reacts with water in the atmosphere to create droplets of sulfuric acid, says Rutgers University environmental scientist Alan Robock. Those droplets are particularly good at scattering the sun's light back out into space. And because sulfur doesn't heat the stratosphere as much as other aerosols, it wouldn't work against the cooling effect. Hydrogen sulfide is an even better candidate for atmospheric seeding than sulfur dioxide, but scientists would...
