although cloud computing has rapidly emerged as a widely accepted computing paradigm, the research on cloud computing is still at an early stage. cloud computing suffers from different challenging issues related to security, software frameworks, quality of service, standardization, and power consumption. efficient energy management is one of the most challenging research issues. the core services in cloud computing system are the saas (software as a service), paas (platform as a service), and iaas (infrastructure as a service). in this paper, we study state-of-the-art techniques and research related to power saving in the iaas of a cloud computing system, which consumes a huge part of total energy in a cloud computing system. at the end, some feasible solutions for building green cloud computing are proposed. our aim is to provide a better understanding of the design challenges of energy management in the iaas of a cloud computing system.  see the full article here at the journal of supercomputing or here
