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 An efficient game-theoretic approach for resource management in Cloud Federation(Institute of Electrical and Electronics Engineers Inc., 2016) Thakur, P.K.; Thomas, M.V.; Chandrasekaran, K.Cloud Federation is an emerging technology for the effective utilization of cloud resources. Effective management of resources is very much required in order to increase the profits of individual CSPs in the federation. Hence, it is of crucial business value for a cloud provider to develop an effective mechanism so that the resource management is efficient in the cloud federation scope. In this paper, we discuss the design and development of game-theoretic approach for the resource management mechanism also considering the trust values between the participating CSPs in the federation. We have discussed and analysed the performance of both the co-operative and non co-operative approaches for the resource allocation. © 2015 IEEE.Item An efficient trust-based Game-Theoretic approach for Cloud Federation Formation(Institute of Electrical and Electronics Engineers Inc., 2016) Dhole, A.; Thomas, M.V.; Chandrasekaran, K.Cloud Federation or a Coalition of Cloud Service Providers (CSPs) is a hot topic nowadays in the industry as well as academia. Cloud Federation was introduced to overcome the realistic limited amount of resources available from a single CSP so that the CSPs may not lose its customers due to the unavailability of resources. But its a challenge to form a Cloud Federation which is stable, reliable and fair in terms of payoff to the CSPs that are part of the Cloud Federation. In this paper, we propose to find a solution to the Cloud Federation formation by following a game-theoretic approach considering the trust between the participating CSPs. This technique will also allow the CSPs to take decision unilaterally based on their own decisions depending on the profit they would receive upon inclusion into the federation. Our approach takes into consideration the trust between the CSPs taking part in the Cloud Federation Formation process. The Game-Theoretic approach used in our approach makes use of a simple Cloud Federation Formation policy which ensures stability and fairness in the Cloud Federation. © 2016 IEEE.Item Virtual Machine Placement in Non-Cooperative Cloud Federation-Alliance(Institute of Electrical and Electronics Engineers Inc., 2023) Addya, S.K.; Satpathy, A.; Turuk, A.K.; Shaoo, B.Many inter-cloud organizations have been proposed to overcome the current limitations of cloud computing, such as service interruption, lack of interoperability, and degradation of services. One such multi-cloud architecture is the cloud federation, where multiple geographically distributed autonomous service providers voluntarily agree to share resources governed by a well-defined set of rules. Although federation offers numerous benefits for the service providers, sharing resources is supervised using a strict set of protocols offering limited flexibility. Hence, this paper proposes a relaxed resources sharing model for the service providers called cloud federation-alliance. The formation of the alliance is modeled as a non-cooperative game among the service providers. The game's stability and the alliance's performance loss are also studied using price-of-stability (PoS) and price-of-anarchy (PoA), respectively. A modified best-fit placement strategy is focused on reducing the power consumed. To assess the performance of the alliance placement, we compare its performance with random and worst-fit allocation techniques. This work aims to build a stable, sustainable, multi-cloud federation alliance and address this structure's critical issues. Extensive simulation results show stability between 2% and 30% with varying workloads. © 2023 IEEE.
