Item Energy aware SLA and green cloud federations(Institute of Electrical and Electronics Engineers Inc., 2016) Joy, N.; Chandrasekaran, K.; Binu, A.Cloud computing has been an emerging research topic since 2007. The online services are delivered as pay-as-you-use in Cloud computing. The customers need not be in a long term contract with Cloud Service Providers (CSPs). Service level agreements (SLAs) are agreements signed between a cloud service provider and customers. Energy aware SLAs extend the existing SLA agreements in order to include energy and carbon aware parameters. The efficiency and availability of the system are not disturbed when certain jobs are relaxed in order to obtain high energy consumption. In order to increase the energy consumption further we incorporated the concept of cloud federations in which a group of CSPs, mutually agree to make use of their resources to execute the VMs of other CSPs. An algorithm based on the amount of energy consumed by different CSPs is being readily implemented. This algorithm grant a group of CSPs to jointly set the federations in a manner to distribute their work equally so as to reduce the energy consumed. The results from the above approach show that it can be considered as a hopeful solution to the problem of reducing the energy cost even though there are a few challenges during implementation. © 2016 IEEE.Item A study on energy efficient cloud computing(Institute of Electrical and Electronics Engineers Inc., 2016) Joy, N.; Chandrasekaran, K.; Binu, A.The rapid increase in demand for computation, increasing amount of data storage needed for running high performance computing enterprises increases the energy and power consumed by large infrastructure. Cloud computing provides a solution to reduce the adverse environmental impacts and saves energy. Our paper draws the attention on the various methods enforced on the cloud environment to make it more energy efficient. In this paper the different energy and power models are being discussed and the main challenges to build a model for green cloud with the help of SLAs are identified. One of the main objectives considered in cloud computing is to provide reliable QoS. This can be defined in the SLA which describes such characteristics. The different ways to minimize energy and power in the cloud computing services are also being discussed in this paper. Our work surveys the various models which will pave the road map for an energy efficient cloud. © 2015 IEEE.
