Power management in cloud computing using green algorithm
R. Yamini · IEEE-International Conference On Advances In Engineering, Science And Management · 2012
The greatest environmental challenge today is global warming, which is caused by carbon emissions. Energy crisis brings green computing, and green computing needs algorithms and mechanisms to be redesigned for energy efficiency. Green IT refers to the study and practice of using computing resources in an efficient, effective and economic way. The various approaches of the green IT are Virtualization, Power Management, Material Recycling and Telecommuting. The basic principles of cloud computing is to make the computing be assigned in a great number of distributed computers rather than local computer or remote server. In fact, cloud computing is an extend of Grid Computing, Distributed Computing and Parallel Computing. It's foreground is to provide secure, quick, convenient data storage and net computing service centered by internet. Currently, a large number of cloud computing systems waste a tremendous amount of energy and emit a considerable amount of carbon dioxide. Thus, it is necessary to significantly reduce pollution and substantially lower energy usage. The analysis of energy consumption in cloud computing consider both public and private clouds. Cloud computing with green algorithm can enable more energy-efficient use of computing power.
