OGSA (Open Grid Services Architecture) is called next-generation grid architecture, which is in the original "five hourglass structure" based on the combination of the latest Web Service technology initiative. OGSA, including two key technologies that grid technology and Web Service technology. With grid computing research, it is increasingly found important grid architecture. Grid architecture is about how to build grid technology, including the grid and the basic function of each part of the definition and description of the relationship between the various parts of the grid and integration method provides an effective operational mechanism characterization of the grid. Clearly, the grid architecture is the skeleton and soul of the grid, the grid is the core technology, only a reasonable grid architecture to be able to design and build a good grid to be able to function effectively mesh.
