High Scalability Building bigger, faster, more reliable websites.

GigaSpaces launched OpenSpaces.org, a community web site for developers who wish to utilize and contribute to the open source OpenSpaces development framework.

OpenSpaces extends the Spring Framework for enterprise Java development, and leverages the GigaSpaces eXtreme Application Platform (XAP) for data caching, messaging and as the container for application business logic. It is designed for building highly-available, scale-out applications in distributed environments, such as SOA, cloud computing, grids and commodity servers. OpenSpaces is widely used in a variety of industries, including financial services, telecommunications, manufacturing and retail -- and across the web in e-commerce, Web 2.0 applications such as social networking sites, search and more.
