IntroductionGreen Cloud Computing

A Cloud is a dynamic, internet optimized

infrastructure for hosting your application.The term comines the !ords green ""meaning en#ironmentally friendly "" and

cloud, the traditional symol for theInternet and the shortened name for atype of ser#ice deli#ery model kno!n

as cloud computing.

The po!er consumption of the pulic cloud storage is ser#ice is aout.- times that of the po!er consumption of the pri#ate cloud storage

ser#ice, at medium and high do!nload rates, due primarily to theincreased energy consumption in transport.

As energy costs are increasing, there is aneed to shift focus from optimising datacentre resource management for pureperformance alone to optimising for energye8ciency !hile maintaining high ser#ice le#elperformance.

9e propose Green Cloud computing modelthat achie#es not only e8cient processingand utilisation of computing infrastructure,ut also minimise energy consumption.
