A QoS and Energy aware Load Balancing and Resource Allocation Framework for IaaS Cloud Providers

The exponential growth of cloud based applications and the increased number of cloud users have given rise to new challenges for cloud service providers, especially for Infrastructure as a Service (IaaS) providers. This exponential growth of datacenters increases the energy consumption, along with its carbon footprints. Hence, better energy aware techniques not only reduce energy costs, but they are also helpful for reducing pollution in the environment. Some of the main challenges for cloud providers include increasing the resource utilization and minimizing energy consumption while maintaining the quality of service (QoS) offered to the users. There are many load balancing and resource allocation techniques proposed to handle these challenges. Out of these techniques, only a few consider QoS goals for IaaS service providers. However, none of these techniques includes service level agreement (SLA) parameters related to the Virtual Machine (VM) life cycle such as VM startup times. In this paper, we propose a novel approach to address this problem.
