Massively distributed systems: From grids and P2P to clouds

Abstract

This keynote describes the evolution of massively distributed computing systems and their key techniques. Clusters of computers now prevail, expand, and become the core components in large-scale computational/ information/data Grids. The Open Grid Service Architecture, specifying the Grid software, protocol, and service standards, are only partially implemented in Globus and other Grid toolkits. Grid security demand globalization among various PKI authorities and interoperability between wired and wireless networks. Very little progress being made in special networks, hardware, languages, and operating systems for Grid/Cloud computing. Business Grids/Clouds are under development by Google, IBM, Sun, Microsoft, etc., and widespread acceptance is hindered by selfish behavior and security concerns. Briefly, the keynote includes rise and fall of computing technologies and hot paradigms in the last 35 Years, and presents the implication that computing clouds over the Internet will be the next battlefield among competitors. © 2008 Springer-Verlag Berlin Heidelberg.
