NEW! Building a grid system using WS-Resource Transfer, Part 4: Using WS-RT for grid monitoring In this five-part "Building a grid system using WS-Resource Transfer" series, we look at the use of WS-Resource Transfer (WS-RT) in different areas of the grid environment -- from using it as a method for storing and recovering general information about grid-to-grid monitoring and management, and security. We also examine how WS-RT can be used for the distribution and division of work. In any grid, there is a huge amount of metadata about the grid that needs to be stored and distributed. Using WS-RT makes sharing the information, especially the precise information required by different systems in the grid, significantly easier. Here in Part 4, we look at both sides of the security session, both in terms of using WS-RT as an aid to the authorization process and at combining WS-Security with WS-RT for secure resource exchange.
