Approaches for Green Computing

Abstract

In past a few years computer paradigm is shifted to remote data centres and the software and hardware services available on the basis of pay for use. This is called Cloud Computing, In which user have to pay for the services Cloud provide the services – Software as a service ,platform as a service and infrastructure as a service .These services provided through the remote data centers (since the data is scattered /distributed over the web.), as Software application and other services migrated on the remote data centre ,management of these data centre in important. Data centre management faces the problem of power consumption. At present cloud computing based system waste a great amount of power and produces co2. Since many servers don’t have a good quality cooling system. Green computing can enable more energy efficient use of computing power .This survey paper show the requirement of green computing and techniques to save the energy by different approaches.
