Power and Performance Issues and Management Approaches in Cloud Computing

Abstract

Cloud computing is a relatively new developing technology that allows users to pay for services on a pay-as-you-go basis. It provides internet-based information and communication technology services, while virtualization enables it to deliver computer resources. Datacenters are the backbone of this technology, consisting of networked computers, cables, power supply units, and other components that host and store corporate data. In cloud datacenters, high performance has always been the most important consideration, but it comes at the expense of power consumption. The key problem is finding a balance between the system's performance and power consumption by lowering power usage without compromising the quality and performance of services. As a result, several attempts are now being done to reduce datacenter energy usage. All concerns relating to energy efficiency are explored and researched in this work. This paper also presents an overview of various power and performance management strategies in cloud computing.
