OGSA is an open standard for service-oriented grids developed by the Global Grid Forum (now the Open Grid Forum) to allow grids to operate as single virtual systems through standardization. It specifies services for infrastructure, execution management, data, resource management, security, self-management, and information. Implementations include the Globus Toolkit which has been used for commercial data centers, severe storm modeling, online media, and national research collaborations.
