The Globus Alliance (http://www.globus.org/) is a community of organizations and individuals developing fundamental technologies behind the "Grid," which lets people share computing power, databases, instruments, and other on-line tools securely across corporate, institutional, and geographic boundaries without sacrificing local autonomy. Since its creation in 1996, the Globus Alliance has been committed to developing open source software, although development was initially carried out by a small number of university research groups. However, since transitioning in 2005 to an open governance model (http://dev.globus.org/), derived from Apache's Jakarta project, the scope of participants has widened to include many more groups around the world, including companies and individuals. Globus currently hosts more than 20 projects, actively developed by a community of more than 100 committers, and spanning a variety of technology concerns on grid systems: common runtime, data management, information management, security, and documentation. Additionally, members of the Globus community can propose new projects which, after an "incubation" process (http://dev.globus.org/wiki/Incubator/Incubator_Process) can escalate to full Globus projects. There are currently more than 25 projects in incubation.
