“…The prior works in [7], [12], [27], [28] assumed that the electricity prices are not affected by the CPs' cooperation. Consequently, they did not consider the impact of the cloud federation on the smart grid as well as how the smart grid takes its decision while taking into account the cooperative workload management of the CPs.…”

Cooperative cloud providers in the form of cloud federations can potentially reduce their energy costs by exploiting electricity price fluctuations across different locations. In this environment, on the one hand, the electricity price has a significant influence on the federations formed, and, thus, on the profit earned by the cloud providers, and on the other hand, the cloud cooperation has an inevitable impact on the performance of the smart grid. In this regard, the interaction between independent cloud providers and the smart grid is modeled as a two-stage Stackelberg game interleaved with a coalitional game in this paper. In this game, in the first stage the smart grid, as a leader chooses a proper electricity pricing mechanism to maximize its own profit. In the second stage, cloud providers cooperatively manage their workload to minimize their electricity costs. Given the dynamic of cloud providers in the federation formation process, an optimization model based on a constrained Markov decision process (CMDP) has been used by the smart grid to achieve the optimal policy. Numerical results show that the proposed solution yields around 28% and 29% profit improvement on average for the smart grid, and the cloud providers, respectively, compared to the noncooperative scheme.

“…Whereas data center ecosystems offer new opportunities for energy-driven management, they also encompass new challenges that must be considered [44,56,10], such as the distant geographic locations of data centers, which have an impact in the migration of VMs (increasing the cost significantly (and the consumed energy) and frequently causing service level degradations for the affected customers) and in the data exchange among VMs located in different data centers (increasing the communication latency among them); the independent administrative domains involved in the ecosystem, which have frequently conflicting goals and do not generally disclose information about their energy consumption and energy mix, thus increasing the need for third parties to independently assess energy data of data centers and share this information within the ecosystem; and the importance of the prediction accuracy of the input data (e.g. workload, energy price, renewable energy), which depends on the predictability of each data source and the prediction window length, and can be a downgrading factor on the efficiency of the management algorithms.…”

Data centers are major contributors to the emission of carbon dioxide to the atmosphere, and this contribution is expected to increase in the following years. This has encouraged the development of techniques to reduce the energy consumption and the environmental footprint of data centers. Whereas some of these techniques have succeeded to reduce the energy consumption of the hardware equipment of data centers (including IT, cooling, and power supply systems), we claim that sustainable data centers will be only possible if the problem is faced by means of a holistic approach that includes not only the aforementioned techniques but also intelligent and unifying solutions that enable a synergistic and energy-aware management of data centers. In this paper, we propose a comprehensive strategy to reduce the carbon footprint of data centers that uses the energy as a driver of their management procedures. In addition, we present a holistic management architecture for sustainable data centers that implements the aforementioned strategy, and we propose design guidelines to accomplish each step of the proposed strategy, referring to related achievements and enumerating the main challenges that must be still solved.

Abstract:Cloud Computing offers on-demand access to computational, infrastructure and data resources operated from a remote source. This novel technology has opened new ways of flexible resource provisions for businesses to manage IT applications and data responding to new demands from customers. In this chapter we give a general insight to the formation and interoperability issues of Cloud Federations that envisage a distributed, heterogeneous environment consisting of various cloud infrastructures by aggregating different IaaS provider capabilities coming from both the commercial and academic area. These multi-cloud infrastructures are also used to avoid provider lock-in issues for users that frequently utilize different clouds. We characterize and classify recent solutions that arose from both research projects and individual research groups, and show how they attempt to hide the diversity of multiple clouds and form a unified federation on top of them. Since they still need to cope with several open issues concerning interoperability, we provide guidelines to address related topics such as service monitoring, data protection and privacy, data management and energy efficiency.
