    MOON: MapReduce On Opportunistic eNvironments

    Abstract—MapReduce offers a flexible programming model for processing and generating large data sets on dedicated resources, where only a small fraction of such resources are every unavailable at any given time. In contrast, when MapReduce is run on volunteer computing systems, which opportunistically harness idle desktop computers via frameworks like Condor, it results in poor performance due to the volatility of the resources, in particular, the high rate of node unavailability. Specifically, the data and task replication scheme adopted by existing MapReduce implementations is woefully inadequate for resources with high unavailability. To address this, we propose MOON, short for MapReduce On Opportunistic eNvironments. MOON extends Hadoop, an open-source implementation of MapReduce, with adaptive task and data scheduling algorithms in order to offer reliable MapReduce services on a hybrid resource architecture, where volunteer computing systems are supplemented by a small set of dedicated nodes. The adaptive task and data scheduling algorithms in MOON distinguish between (1) different types of MapReduce data and (2) different types of node outages in order to strategically place tasks and data on both volatile and dedicated nodes. Our tests demonstrate that MOON can deliver a 3-fold performance improvement to Hadoop in volatile, volunteer computing environments

    Technology market intermediaries to facilitate external technology exploitation: The case of IP auctions

    Get PDF
    Recently the phenomena of external technology exploitation (ETE) has started to attract attention from scholars, businesses and politicians likewise alongside with a growth of the markets for technology. However, the markets for technology are still characterized by inhibiting obstacles that lead to high transaction costs, thus prohibit efficient transactions and result in market failure. Although, on the one hand the presence of obstacles lead to high transaction costs, the large market potential on the other hand provides incentives for technology market intermediaries (TMI) to develop new exploitation models to facilitate ETE transactions by reducing transaction costs. Throughout this paper we address the general research question of whether and how new exploitation models can actually facilitate ETE. To address this question, in a first step we generate insights into TMIs acting on the markets for technology and derived a conceptual basis for a further understanding of TMIs. Having carried out a detailed review of the literature, we develop a theory based typology for six TMI archetypes. Throughout this exercise we gain insights into the variety of different functions TMIs have on the markets for technology and various new ways how TMIs try to facilitate ETE transactions. Throughout the second part of this paper, we focus on IP auctions as one particular business model of the archetype “IP Broker”. We investigate this “young” business model presenting first insights into two qualitative studies. In a first step we derive a generic IP auction process based on a qualitative, empirical analysis of IP auction processes. We then translate these results into a theory based process view and derive a generic IP auction process as a specific type of an ETE process. Having thus generated a close understanding of the transaction process, we presented results from four cases of successful transactions, i.e. where patents were sold for particular high prices from two SMEs and two MNCs. The case studies are analyzed according to four main aspects including characteristics of the companies that exploited patented technologies (including motives and selection processes), the patented technology as such, the organization of the transaction and the companies’ perceptions regarding the success of the transactions. --

    This paper provides both an update concerning the setting up of the European DARIAH infrastructure and a series of strong action lines related to the development of a data centred strategy for the humanities in the coming years. In particular we tackle various aspect of data management: data hosting, the setting up of a DARIAH seal of approval, the establishment of a charter between cultural heritage institutions and scholars and finally a specific view on certification mechanisms for data

    De Multilatina a Latina Global: Descubriendo las elecciones a nivel corporativo sobre estrategia de internacionalización del Grupo Nutresa

    Get PDF
    Research on Multilatinas has underexplored multinationals from Colombia and their corporate-level international strategy choices to develop into Global Latinas. Building on interviews, documents, and archival data about Grupo Nutresa –Colombia’s most international firm in manufactured goods–, this study unveils and discusses this firm’s corporate-level international strategy choices between 1960 and 2014. A prevailing notion is that most multinationals from Latin America continue to target international operations to focus mainly on their home region through an export, multidomestic or transnational corporate-level international strategy. In contrast, data show that Grupo Nutresa chose to evolve through a sequential approach from an export to a transnational corporate-level international strategy while its international operations were able to transcend its home region to reach North America, Asia, Europe, Africa, and Oceania. These results add to international business research on emergent market multinational companies (EMNCs) from Latin America by unveiling the corporate-level international strategy choices of a Colombian origin Multilatina that transformed into a Global Latina.Las investigaciones sobre Multilatinas han estudiado poco a las multinacionales de origen colombiano y las elecciones a nivel corporativo que estas empresas han realizado sobre su estrategia de internacionalización para convertirse en Latinas Globales. A partir de entrevistas, documentos y datos de archivo sobre el Grupo Nutresa –la empresa colombiana más internacional de bienes manufacturados–, este estudio descubre y discute las elecciones a nivel corporativo que esta empresa realizó sobre su estrategia de internacionalización entre los años 1960 y 2014. Una noción que prevalece acerca de la mayoría de multinacionales de América Latina, es que estas empresas continúan dirigiendo sus operaciones internacionales principalmente hacia su región a través de una estrategia de internacionalización a nivel corporativo exportadora, multidoméstica o transnacional. En contraste, los datos evidencian que el Grupo Nutresa eligió evolucionar a través de un proceso secuencial de una estrategia de internacionalización a nivel corporativo exportadora a una transnacional, mientras que sus operaciones internacionales lograron trascender su región para llegar a Norteamérica, Asia, Europa, África, y Oceanía. Estos resultados aportan a la investigación en negocios internacionales sobre multinacionales de mercados emergentes, particularmente de América Latina, al descubrir y discutir las elecciones a nivel corporativo sobre estrategia de internacionalización de una Multilatina de origen colombiano que se transformó en Latina Global.

    A typology of technology market intermediaries

    Get PDF
    Technology Market Intermediaries (TMI) are currently emerging on the markets for technologies attempting to realize business opportunities and facilitate the technology and IP transactions supporting firms and other markets actors (e.g. universities). They aim to support open innovation, respectively facilitate more economically technology and particularly IP transactions. However, our understanding of TMIs and their roles needs to be considered incomplete. In this paper I provide evidence on the growing number of TMIs and derived a conceptual basis for a further understanding of TMIs. The inherent difficulties of intellectual property monetization present a challenge for technology based enterprises and business opportunities for IP firms. Following a literature review, I develop a typology for TMIs. Having carried out a review of the literature I compiled a mix of primary and secondary data on about 70 TMIs. Applying the 'nine business model building blocks' from Osterwalder (2004) I identify 12 different TMI types which I then consolidate into six TMI archetypes using the framework for 'business models archetypes' of Herman and Malone (2003). --typology,type,Technology Market Intermediaries

    The growing complexity of content delivery networks: Challenges and implications for the Internet ecosystem

    Get PDF
    Since the commercialization of the Internet, content and related applications, including video streaming, news, advertisements, and social interaction have moved online. It is broadly recognized that the rise of all of these different types of content (static and dynamic, and increasingly multimedia) has been one of the main forces behind the phenomenal growth of the Internet, and its emergence as essential infrastructure for how individuals across the globe gain access to the content sources they want. To accelerate the delivery of diverse content in the Internet and to provide commercial-grade performance for video delivery and the Web, Content Delivery Networks (CDNs) were introduced. This paper describes the current CDN ecosystem and the forces that have driven its evolution. We outline the different CDN architectures and consider their relative strengths and weaknesses. Our analysis highlights the role of location, the growing complexity of the CDN ecosystem, and their relationship to and implications for interconnection markets.EC/H2020/679158/EU/Resolving the Tussle in the Internet: Mapping, Architecture, and Policy Making/ResolutioNe
