Roundhouse is a modular J2EE application platform that allows applications to combine Struts modules, JSR-168 portlets, and Web services into a single application. It is intended to take the drudgery out of new J2EE application development by providing existing user and security architecture, navigation, and logging although it can be used standalone with no additional development. It ships with forum and blog modules along with several handy portlets which essentially make it a a portal based blog and forums application. The architecture is Struts-based and includes a Struts-based JSR-168 Portlet container. Developers extend Roundhouse by creating new standalone modules which can be independently developed without mucking around in the Roundhouse codebase and merged with Roundhouse and any number of other modules at build time. Modules can be created, packaged as MARF files, and redistributed.
By adding a user-friendly interface, predefined best practices, and fine-grained compliance reporting to your own IT configuration rules, Rudder enables enterprises to rapidly benefit from increased productivity and insight throughout their IT operations. It can measure the drift of IT infrastructures. It enables you to automate installation and configuration of services, continuously verify and repair them, and centralize information and knowledge about your infrastructure and generate compliance reports, helping you analyze and control the deviation between a service’s current state and its nominal behavior.
RunDeck is a command automation hub that helps you automate ad-hoc and routine procedures in data center or cloud environments. It allows you to run tasks on any number of nodes from a Web-based or command-line interface. It also includes other features that make it easy to scale up your scripting efforts, including access control, workflow building, scheduling, logging, and integration with external sources for node and context data.
RunJRun is a very simple system for doing parallel processing in Java, using Amazon Elastic Compute Cloud (EC2) instances as compute nodes. The basic compute unit is a Runnable, Serializable Java object, a "task" for short. A user submits a list of such tasks to RunJRun. Each task then has its run() method invoked on an EC2 instance. To use it, you'll need an Amazon Machine Image (AMI) that has the RunJRun server-side software installed; several such AMIs are available.
Rythm Template Engine is a general-purpose, high-performance Java template engine which uses a Razor-like syntax. It is 2-to-3 times faster than Velocity. It supports variables, expression evaluation, control flow (if-else-if), looping, template inheritance(decoration/layout), and many features. There is a Play!Framework plugin based on Rythm. You can use Rythm in any place to generate any type of text file, including HTML, XML, Json, SQL, and any kind of source code.
SBuild is a Scala-based build system. It features platform independence, multi project support, automatic detection of needed actions, automatic up-to-date detection, a flexible scheme handler mechanism, Maven repository support, Ant task integration, automatic cross-project resolving of dependencies, high speed, a simple "syntax" that requires almost no Scala knowledge, behind-the-sceens compilation of build script to bytecode for fast execution time, and built-in scheme handlers for HTTP and Maven.
