Multi-Class load balancing scheme for QoS and energy conservation in cloud computing

Abstract

The challenges of adhering to stringent Quality of Service requirements, efficiently utilize resources, and conserve energy consumption are constantly being faced by Cloud Service Providers. In a bid to proffer solutions to these challenges, numerous researchers have proposed varied solutions. However, there has yet to be an all-encompassing solution that tackles all these challenges at once, as these challenges are often times contrasting. Authors therefore usually focus on one then seek to manage the compromises on the other(s). In this work, we propose a new scheme for load balancing that uses multiple workload classes to guarantee end-to-end QoS while conserving energy with little compromise on either. Experiments were done using CloudSim toolkit and obtained results show that our scheme outperforms the other approaches both in terms of energy conservation and QoS adherence.
