« The Apache™ Hadoop™ project develops open-source software for reliable, scalable, distributed computing.
The Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using a simple programming model. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-avaiability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-availabile service on top of a cluster of computers, each of which may be prone to failures. »
"The CCR and DSS Toolkit delivers delivers a set of .NET and Compact Framework class libraries and tools that enable developers to better deal with the inherent complexities in creating loosely-coupled concurrent and distributed applications."
Prophet is a new kind of database that offers peer-to-peer opportunistic replication (it's basically like a database version of the Sync framework). It's a very lightweight semi-relational database.
SD (Simple Defects) is a bug tracking tool based on Prophet that is not-only peer-to-peer, but it syncs with other bug tracking tools!
DryadLINQ is a Microsoft Research project, which aims to make distributed computing on clusters of computers simple enough for all programmers. DryadLINQ combines another Microsoft Research technology, Dryad, with the familiar LINQ technology from the Microsoft .NET framework.
