ABSTRACT
Green Computing is one the recent trends that’s growing with a tremendous phase in IT sector. Now each company are following the green principles before the design of their systems. Green computing helps in reducing the pollution and destruction of environment. The basic principles that are followed here are green disposal, green design and green manufacturing, which are achieved through a series of ways like power management, green data center, e-waste disposal and virtualization etc,. Here we look at detailed view of virtualization. Firstly we look at all the four levels in a glance, then we look more deep on each level and we see the way of achieving it with good real time examples. Then we go on to look into the embodied energy and the other new levels of virtualization. Finally we look about getting a return on the embodied energy costs of buying a new virtualization server.
INTRODUCTION
Green Computing is the study and practice of using computing resources efficiently. Typically, green computing systems or products take into account the so-called triple bottom line of people, planet, and profit. This differs somewhat from traditional or standard business practices that focus mainly on the economic viability of a computing solution. These focuses are similar to those of green chemistry; reduction of the use of hazardous materials such as lead at the manufacturing and recycling stages, maximized energy efficiency during the product's lifetime, and recyclability or biodegradability of both a defunct product and of any factory waste. It is "the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems—efficiently and effectively with minimal or no impact on the environment. Thus, green IT includes the dimensions of environmental sustainability, the economics of energy efficiency, and the total cost of ownership, which includes the cost of disposal and recycling.
With increasing recognition that man-made greenhouse gas emissions are a major contributing factor to global warming, enterprises, governments,and society at large now have an important new agenda: tackling environmental issues and adopting environmentally sound practices. Greening our IT products, applications, services, and practices is both an economic and an environmental imperative, as well as our social responsibility. Therefore, a growing number of IT vendors and users are moving toward green IT and thereby assisting in building a green society and economy.
CONCLUSION
There is a compelling need for applications to take environmental factors into account in their design, driven by the need to align with organizational environmental policies, reduce power and infrastructure costs and to reduce current or future carbon costs. The potential reduction in energy and emissions footprint through good architectural design is significant. The move to more environmentally sustainable applications impacts software and infrastructure architecture. The link between the two is strong, driving a need for joint management of this area of concern from infrastructure and software architects within organizations. These issues should be considered at the outset and during a project, not left to the end. An interesting observation is that our principles also align well with the traditional architectural drivers. Does this mean that energy reduction can be used as a proxy for all the other drivers? An architecture designed solely to reduce energy over the full lifecycle would seem to also result in a ―good‖ architecture from a broader perspective.
