„Banking is necessary, banks are not.“ konstatierte Bill Gates mit Verweis auf das Online-Banking in den 90er Jahren sehr polemisch . Das Aufkommen des Online-Banking schien die Bankfiliale und den Banker überflüssig werden zu lassen. Tatsächlich lassen sich heute viele Finanzdienstleistungen ohne den persönlichen Kontakt zu einem Berater vom Kunden online erledigen. Überflüssig sind Filialen und Berater bisher deshalb aber nicht geworden, denn die Nachfrage nach Information und Beratung steigt immer noch an. Einige Jahre später mit dem Aufkommen von Social Software, stellt sich eher die Frage, auf welchen Wegen Kunden sich informieren und ihren Bedarf nach Information decken. Was bisher meist durch den Berater geschehen ist, passiert heute oft durch Recherche und Austausch Gleichgesinnter im Internet. Im Bereich kleiner Privatkredite und –anlagen geraten Banken verstärkt durch P2P -Banking-Portale unter Druck. Dieses Thema gewann im Zuge der Reputationsverluste der Banken während und nach der Finanzkrise und der sich ständig weiterentwickelnden Möglichkeiten des Internets an Aktualität. Das Vertrauen in Kreditinstitute hat gelitten. Kunden fühlen sich verunsichert und nicht in der Lage das Risiko einer Anlage mit Hilfe des Beraters adäquat einzuschätzen, weil die Beratungsleistung in manchen Fällen von zweifelhafter Qualität ist. So ist es nachvollziehbar, dass der Wunsch besteht, die klassischen Finanzintermediäre zu meiden. Communities, Blogs und Foren spielen heute für viele Kunden bei der Anlageentscheidung eine größere Rolle als die Beratung in der Bank. Doch nicht nur die Beratung wird durch die User selbst organisiert. Auch eine Kernaufgabe der Banken, nämlich die Finanzintermediation wird durch gemeinschaftliche Selbstorganisation substituiert und Kreditinstitute werden teilweise oder ganz aus diesem Prozess ausgeschlossen. Neben den sozialen Motiven locken die augenscheinlich günstigen Zinssätze auch den ertragsorientierten Anleger und den kostenbewussten Schuldner auf die P2P -Banking-Portale. Die Interaktivität und Schnelllebigkeit des Web 2.0 spielt hier eine große Rolle und ist im Begriff die Finanzdienstleistungsbranche in ähnliche Veränderungsdynamiken zu zwingen. Gleichzeitig verpassen Banken den Anschluss beim Ausschöpfen der Möglichkeiten des Web 2.0 und damit auch die Chance ihren angeschlagenen Ruf zu verbessern und neue Geschäftsmodelle zu etablieren.

Grids, P2P and Services Computing, the 12th volume of the CoreGRID series, is based on the CoreGrid ERCIM Working Group Workshop on Grids, P2P and Service Computing in Conjunction with EuroPar 2009. The workshop will take place August 24th, 2009 in Delft, The Netherlands. Grids, P2P and Services Computing, an edited volume contributed by well-established researchers worldwide, will focus on solving research challenges for Grid and P2P technologies. Topics of interest include: Service Level Agreement, Data & Knowledge Management, Scheduling, Trust and Security, Network Monitoring and more. Grids are a crucial enabling technology for scientific and industrial development. This book also includes new challenges related to service-oriented infrastructures. Grids, P2P and Services Computing is designed for a professional audience composed of researchers and practitioners within the Grid community industry. This volume is also suitable for advanced-level students in computer science.

Master Thesis from the year 2007 in the subject Computer Science - General, grade: 1,3, Technical University of Darmstadt, 47 entries in the bibliography, language: English, abstract: In this thesis existing mathematical models for P2P systems are presented and evaluated. Thereby the search efficiency in structured and unstructured P2P overlays, the features and restrictions in P2P streaming applications, the service capacity in P2P file sharing systems, content download and replication times in P2P networks and many other issues are investigated.Furthermore the new extended model, possibly combining the most essential characteristics of P2P systems in a consistent way is presented. The characteristicsobserved in the new model are categorized in three groups according to the P2P system properties being described: the overlay parameters, the characteristics of participating peers and the resource and service characteristics.Thereafter the objectives, regulated by P2P applications' users and providers, and aspects of underlying P2P systems they are interested in are observed. We consider the P2P applications Skype, Joost and KaZaA, differentiating between the application users and providers, and analyzing the technical view on the P2P system characteristics.A wide variety of existing P2P systems integrating the insights of distributed systems, databases, complexity theory and many other research areas raised inconsistencies and incompatibilities in used terminologies and abstractions. Therefore providing P2P systems interoperability and creating a common model applicable for all P2P systems became a desirable goal. In this thesis the existing P2P layer architectures considering P2P systems as a set of layers ordered according to their increasing degree of abstraction are presented. Furthermore each model layer, its input, output and functionality are described individually.

Peer-to-Peer ( P2P ) applications have witnessed unprecedented growth on the Internet and are increasingly being used for real-time applications such as video conferencing and live streaming. The design of the majority of P2P systems today, however, does not strive to achieve any systematic optimization of the total value to all peers under a resource sharing constraint. This may well be the next step in improving the performance of P2P systems.

The Internet community has recently become interested in distributed query processing. Not surprisingly, they approach this problem from a very different angle than the traditional database literature. The fundamental goal of Internet systems is to operate at very large scale (thousands if not millions of nodes). To achieve this degrees of scale, these system sacrifice transparency and/or flexibility.
