Sažetak
Cloud Computing represents the most promising Information and Communication Technology (ICT) paradigm that is directlyor indirectly used by almost every online user. Its ultrascale size requires large data centers comprising several thousands of serversand other supporting equipment. The power consumption share of such infrastructures reaches 1.1% to 1.5% of the total electricityuse worldwide, and is projected to rise even more. In this paper, we describe recent trends in Cloud Computing regarding theenergy efficiency of its supporting infrastructure. We present the state of the art approaches found in literature and in practicecovering servers, networking, Cloud management systems and appliances, which consists of a software utilized by end users. We describe benefits and trade-offs when applying energy efficiency techniques, and finally we extract existing challenges andhighlight future research directions.
