GridGain
We develop GridGain - a Java-based open source grid computing infrastructure. GridGain is free and is dual licensed under LGPL and Apache 2.0 licenses. It is built in Java and for Java and embodies the best the modern Java 5 programming model has to offer.
Overview
The core of our product philosophy is powerful and elegant simplicity. Simplicity never comes cheap. It does not come from removing features or by dumbing them down - it comes from a deep understanding of how grid computing is used in a real life, how developers will code against it and how features "click" together in a cohesive design.
We take the same cue towards removing clutter and providing distilled refinement in developer's productivity as other frameworks like Spring, Seam and Grails. Most of our customers have their first examples working in less than 30 minutes - and that's usually less than it takes to just download and install other grid computing frameworks.
The purpose of any grid computing framework is to provide parallelization of processing. Processing can mean many things like computation, data storage, running builds, analyzing big sets of data, searching, image recognition, etc. Parallelization of processing always leads to an improved scalability and performance.
