The utility computing model introduced by cloud computing combined with the rich set of cloud infrastructure services offers a very viable alternative to traditional servers and computing clusters. MapReduce distributed data processing architecture has become the weapon of choice for data-intensive analyses in the clouds and in commodity clusters due to its excellent fault tolerance features, scalability...
Workflows have emerged as a paradigm for representing and managing complex distributed computations and are used to accelerate the pace of scientific progress. A recent National Science Foundation workshop brought together domain, computer, and social scientists to discuss requirements of future scientific applications and the challenges they present to current workflow technologies.
Discusses the emergent World Wide Web-based distributed environments for high-performance computing and communications (HPCC) on the National Information Infrastructure (NII) with the focus on Java as an enabling technology. We start with a review of the past, present and near-term future of the "Java phenomenon", exposed in the background of some related previous approaches towards a distributed...
