A Review Study on Energy Consumption in Cloud Computing

Abstract

Cloud computing has become a fundamental technology for a wide range of computing services, yet its increasing energy demands present substantial environmental and economic challenges. With the rapid growth of Cloud services and applications, increasing number of researches have been focused on energy saving. The need to reduce energy costs is a constant challenge of cloud providers and data centers. This paper offers an extensive review of the issues surrounding energy consumption in cloud computing, with a focus on algorithms associated with the situational awareness, consolidation, allocation, placement/migration, and scheduling of virtual machines and containers. We conduct a critical analysis of studies from 2018 to 2023, comparing various methodologies aimed at achieving energy efficiency without sacrificing performance. This review delineates current trends, identifies gaps in existing research, and proposes directions for future investigations. Our study emphasizes the necessity of cultivating sustainable practices in cloud computing and provides valuable insights into the practical implementation of energy-efficient solutions in cloud environments.
