Energy-Efficient Management of Data Center Resources for Cloud Computing: A Vision, Architectural Elements, and Open Challenges

Cloud computing is offering utility-oriented IT services to users worldwide. Based on a pay-as-you-go model, it enables hosting of pervasive applications from consumer, scientific, and business domains. However, data centers hosting Cloud applications consume huge amounts of energy, contributing to high operational costs and carbon footprints to the environment. Therefore, we need Green Cloud computing solutions that can not only save energy for the environment but also reduce operational costs. This paper presents vision, challenges, and architectural elements for energy-efficient management of Cloud computing environments. We focus on the development of dynamic resource provisioning and allocation algorithms that consider the synergy between various data center infrastructures (i.e., the hardware, power units, cooling and software), and holistically work to boost data center energy efficiency and performance. In particular, this paper proposes (a) architectural principles for energy-efficient management of Clouds; (b) energy-efficient resource allocation policies and scheduling algorithms considering quality-of-service expectations, and devices power usage characteristics; and (c) a novel software technology for energy-efficient management of Clouds. We have validated our approach by conducting a set of rigorous performance evaluation study using the CloudSim toolkit. The results demonstrate that Cloud computing model has immense potential as it offers significant performance gains as regards to response time and cost saving under dynamic workload scenarios.Comment: 12 pages, 5 figures,Proceedings of the 2010 International Conference on Parallel and Distributed Processing Techniques and Applications (PDPTA 2010), Las Vegas, USA, July 12-15, 201

Global economics governance in the post-crisis world

The Great Crisis has made it clear once again that avoiding the derailment of globalization of trade and finance and the protecting the globe from fragmentation call for enhanced global cooperation and an efficient, flexible and coherent system of global governance. Three interconnected levels (national, regional, and global) comprise the system of global governance. This paper is dealing with some of the main issues of global economic governance in the post-crisis world. It reveals that the turbulence and the distress of the world of the early 21st century have deeper roots and broader sources than the crisis. Global governance therefore has to respond much broader set of challenges in comprehensive framework and long term perspective

InterCloud: Utility-Oriented Federation of Cloud Computing Environments for Scaling of Application Services

Cloud computing providers have setup several data centers at different geographical locations over the Internet in order to optimally serve needs of their customers around the world. However, existing systems do not support mechanisms and policies for dynamically coordinating load distribution among different Cloud-based data centers in order to determine optimal location for hosting application services to achieve reasonable QoS levels. Further, the Cloud computing providers are unable to predict geographic distribution of users consuming their services, hence the load coordination must happen automatically, and distribution of services must change in response to changes in the load. To counter this problem, we advocate creation of federated Cloud computing environment (InterCloud) that facilitates just-in-time, opportunistic, and scalable provisioning of application services, consistently achieving QoS targets under variable workload, resource and network conditions. The overall goal is to create a computing environment that supports dynamic expansion or contraction of capabilities (VMs, services, storage, and database) for handling sudden variations in service demands. This paper presents vision, challenges, and architectural elements of InterCloud for utility-oriented federation of Cloud computing environments. The proposed InterCloud environment supports scaling of applications across multiple vendor clouds. We have validated our approach by conducting a set of rigorous performance evaluation study using the CloudSim toolkit. The results demonstrate that federated Cloud computing model has immense potential as it offers significant performance gains as regards to response time and cost saving under dynamic workload scenarios.Comment: 20 pages, 4 figures, 3 tables, conference pape

Review of Literature and Curricula in Smart Supply Chain & Transportation

This study provides a review of existing smart supply chain management (SCM) literature and current course offerings in order to identify unexplored implications of smart SCM. Specifically, the study focuses on curricula within the state of California to derive potential opportunities for the relevant practitioners in the Bay Area. In addition, the study further extends curriculum review to other well-recognized SCM programs around the U.S. By exploring current relevant course offerings from different academic institutions for higher education (i.e., universities), this research aims to deliver general ideas useful to knowledge practitioners in fields concerning SCM. Finally, the research illustrates a conceptual framework aimed at fostering familiarity with the necessary research topics for the evolving smart SCM

Early Learning Innovation Fund Evaluation Final Report

This is a formative evaluation of the Hewlett Foundation's Early Learning Innovation Fund that began in 2011 as part of the Quality Education in Developing Countries (QEDC) initiative.  The Fund has four overarching objectives, which are to: promote promising approaches to improve children's learning; strengthen the capacity of organizations implementing those approaches; strengthen those organizations' networks and ownership; and grow 20 percent of implementing organizations into significant players in the education sector. The Fund's original design was to create a "pipeline" of innovative approaches to improve learning outcomes, with the assumption that donors and partners would adopt the most successful ones. A defining feature of the Fund was that it delivered assistance through two intermediary support organizations (ISOs), rather than providing funds directly to implementing organizations. Through an open solicitation process, the Hewlett Foundation selected Firelight Foundation and TrustAfrica to manage the Fund. Firelight Foundation, based in California, was founded in 1999 with a mission to channel resources to community-based organizations (CBOs) working to improve the lives of vulnerable children and families in Africa. It supports 12 implementing organizations in Tanzania for the Fund. TrustAfrica, based in Dakar, Senegal, is a convener that seeks to strengthen African-led initiatives addressing some of the continent's most difficult challenges. The Fund was its first experience working specifically with early learning and childhood development organizations. Under the Fund, it supported 16 such organizations: one in Mali and five each in Senegal, Uganda and Kenya. At the end of 2014, the Hewlett Foundation commissioned Management Systems International (MSI) to conduct a mid-term evaluation assessing the implementation of the Fund exploring the extent to which it achieved intended outcomes and any factors that had limited or enabled its achievements. It analyzed the support that the ISOs provided to their implementing organizations, with specific focus on monitoring and evaluation (M&E). The evaluation included an audit of the implementing organizations' M&E systems and a review of the feasibility of compiling data collected to support an impact evaluation. Finally, the Foundation and the ISOs hoped that this evaluation would reveal the most promising innovations and inform planning for Phase II of the Fund. The evaluation findings sought to inform the Hewlett Foundation and other donors interested in supporting intermediary grant-makers, early learning innovations and the expansion of innovations. TrustAfrica and Firelight Foundation provided input to the evaluation's scope of work. Mid-term evaluation reports for each ISO provided findings about their management of the Fund's Phase I and recommendations for Phase II. This final evaluation report will inform donors, ISOs and other implementing organizations about the best approaches to support promising early learning innovations and their expansion. The full report outlines findings common across both ISOs' experience and includes recommendations in four key areas: adequate time; appropriate capacity building; advocacy and scaling up; and evaluating and documenting innovations. Overall, both Firelight Foundation and TrustAfrica supported a number of effective innovations working through committed and largely competent implementing organizations. The program's open-ended nature avoided being prescriptive in its approach, but based on the lessons learned in this evaluation and the broader literature, the Hewlett Foundation and other donors could have offered more guidance to ISOs to avoid the need to continually relearn some lessons. For example, over the evaluation period, it became increasingly evident that the current context demands more focused advance planning to measure impact on beneficiaries and other stakeholders and a more concrete approach to promoting and resourcing potential scale-up. The main findings from the evaluation and recommendations are summarized here
