Reliable and Energy Efficient Resource Provisioning and Allocation in Cloud Computing

Abstract:
Reliability and Energy-efficiency is one of the biggest trade-off challenges confronting cloud services providers. To maximize the reliability of the cloud computing services, all the cloud service vendors add back-up resources and use replication as well as load balancing as fault tolerance mechanism. Adding extra resources increase energy consumption more steeply that the reliability. The key technique used to reduce the energy consumption is by running the resources on a low power scaling level or by turning off the under-utilized or idle resources such as back-up by migrating the running virtual machines (VM) from the under-utilized resources to other resources. Turning off the backup resources will reduce the reliability of the system. For example, if a physical machine fails due to some hardware or software issues before the completion of tasks and there are no recovery/back-up resources, then all the VMs and their corresponding processes will have to start again. This will dramatically increase overheads such as energy consumption and resource utilization. This creates a critical trade-off between the reliability and energy efficiency of the cloud computing systems. In order to reach equilibrium, there is a distinct need to focus on the optimization of relationship between reliability and energy efficiency of cloud computing systems by providing reliability and energy aware resource provisioning and VM allocation algorithms and system architectures.
