Cloud computing provides different computing services (e.g. networks, servers, storage, applications, and services) that can be accessed over internet with less maintenance and less management efforts. But normal IT equipment uses more energy if companies will not shift to green computing. This paper focuses on the ways to shift on green cloud and it benefits. KEYWORDS: Cloud, Cloud Computing, Green Cloud Computing, Management, Virtualization I. INTRODUCTION Green computing is the study and practice of environmentally sustainable computing which includes e-waste management and also reduces resource use. Similarly green cloud computing focuses on environment, with cloud computing, provides services that runs on vendor’s system which helps in minimizing the cost of building other infrastructure and services to run, hence also makes a green and clean environment. Cloud computing allows us to run (programs, services) at high utilization of resources; an introduction of the paper should explain the nature of the problem, we can use fewer number of computers. This allows us to have higher utilization, saving on environment cost of building those computers [1]. As the energy demand in computing is increasing, the methods for the efficient use of energy are needed. In this paper we are going to explore how virtualization will help in building a green cloud computing and CLEER model which will help to make a green cloud computing environment. II. GREEN COMPUTING Green computing, also known as green technology, is responsible for use of computers and related resources keeping eco-friendly environment. It includes central processing units (CPU), servers and peripherals as well as reduced resource consumption and proper disposal of ewaste (harmful gases and heat).

International Journal of Electronics and Communication Engineering & Technology (IJECET), ISSN 0976 – 6464(Print), ISSN 0976 – 6472(Online), Special Issue (November, 2013), © IAEME Environment eco-friendly infrastructure is need. Energy Star, first voluntary labelling program started by United States towards green computing. It was conceived by Environmental Protection Agency (EPA) in 1992 to promote energy efficiency in hardware of all kinds. Most IT department have initiated some projects or adopted various techniques to reduce the environmental impact of their IT operations. The major problem faced by an organization while implementing energy efficient and ecofriendly technologies is the difficulty in measuring saved energy, effective cost. Therefore, the Green Grid, a global consortium of organization come out with one of the best way to reduce environmental impact that is virtualization. Virtualization is technique to run applications and software virtually. III. VIRTUALIZATION Virtualization provides a platform for optimizing complex IT resources in scalable manner. This makes the cloud computing cost effective. Virtualization refers to the creation of virtual version of device or resources, such as a server, storage device, and network, operating system where the framework divides the resource into one or more execution environment. Virtualization consists of a system administrator that combine physical system into VM in best energy efficient manner. In a research based on five setup scenario, on premise with no virtualization; on premise with virtualization; colocation with no virtualization; private cloud and public cloud, found that on site server with no virtualization will emit about 46Kg of CO2 per year. The figure will touch 2 Kg if a person using a public cloud confirming to best practice [2].It can be concluded that running business applications and services on cloud can be more carbon and energy efficient compared to running it locally. It has been found that IT industry energy consumption is 2% of the global energy usage [3]. Moving towards virtualization and using cloud services will reduce the energy consumption. System virtualization creates many virtual systems within a single physical system. So working on virtualized system resources which are run by Hypervisors are used. A hypervisor is a software or/and firmware that provides a virtual machine and provide direct access on underlying hardware but within some constrained. Fig.1 shows virtualization with hypervisor OS.

International Journal of Electronics and Communication Engineering & Technology (IJECET), ISSN 0976 – 6464(Print), ISSN 0976 – 6472(Online), Special Issue (November, 2013), © IAEME There are two types of hypervisors: Type 1 and Type 2. Type 1 hypervisors run directly on the system hardware. Type 2 hypervisors run on a host OS that provides virtualization services. Fig. 1 shows types of hypervisors. Fig. 2: Type 1 and Type 2 Hypervisors According to a new research from Pike Research [4], the global market for green data centers will grow from $17.1 billion in 2012 to $45.4 billion by 2016.This is necessary in green cloud computing point of view to less power consumption. IV. CLEER MODEL Cloud Energy and Emission Research Model (CLEER) is an open access model for accessing the net energy and emissions implications of cloud services at different levels of market acceptance. This model aims to provide full transparency on calculations and input values assumptions so that its results can be duplicated and its methods and data can be refined and improved by research community. According to CLEER model, moving common application and code such as email, spreadsheet, and CRM software to the cloud will save a large amount of energy. According to the research by Lawrence Berkeley National Laboratory and Northwestern University, it was found that the amount of energy that can be saved is 87% or 326 petajoules [5], roughly 23 billion KWh that is enough electricity needed to power Los Angeles for one year.

In addition to energy analysis research community, it is also useful to those in the business and policy communities who want to understand the environmental implication of shifts to cloud services. A. U.S. Case Study In the U.S. study, there were three common business software applications which were chosen for analysis in the CLEER model and assessed the technical potential for energy and emissions savings that might be realized if these three software applications were fully shifted to the cloud across the U.S. workforce [6]. There chosen applications were email, productivity software, and CRM software which are most commonly used software applications at workplaces.

International Journal of Electronics and Communication Engineering & Technology (IJECET), ISSN 0976 – 6464(Print), ISSN 0976 – 6472(Online), Special Issue (November, 2013), © IAEME According to the report as shown in Table 1, a comparison is being made between how much energy consumption, a cloud based software system and present day system make. V. CONCLUSION Green computing leads to many difficulties in establishing the energy efficient system but it has great impact on environment. A large amount of energy can be saved using cloud for running business applications. Shifting on cloud helps to reduce infrastructure cost, maintenance cost and also helps in making a green environment. Using virtualization to run business applications and accepting, improvising and optimizing the CLEER model will save high percentage of energy. VI.
