Apache ZooKeeper is an effort to develop and maintain an open-source server which enables highly reliable distributed coordination. What is ZooKeeper? ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All of these kinds of services are used in some form or another by distributed applications. Each time they are implemented there is a lot of work that goes into fixing the bugs and race conditions that are inevitable. Because of the difficulty of implementing these kinds of services, applications initially usually skimp on them ,which make them brittle in the presence of change and difficult to manage.

Welcome to Apache™ Hadoop™! What Is Apache Hadoop? The Apache™ Hadoop® project develops open-source software for reliable, scalable, distributed computing. The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. 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-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures.

Apache Aries - Index Apache Aries - Index The Aries project consists of a set of pluggable Java components enabling an enterprise OSGi application programming model. This includes implementations and extensions of application-focused specifications defined by the OSGi Alliance Enterprise Expert Group (EEG) and an assembly format for multi-bundle applications, for deployment to a variety of OSGi based runtimes. The OSGi R4 V4.2 Enterprise Specification can be found here: http://www.osgi.org/Download/Release4V42 To understand the complete scope of the Aries project, see the Aries proposal document on the incubator wiki. To understand how to use Aries components, take a look at the BlueprintHelloWorldTutorial pages which guides you through how to build the Aries code, provides sample applications and describes how to set up an environment in which to run the consuming application.
