You've got grid Just because users are on a device


You've got grid
Just because users are on a device such as a cell phone or PDA doesn't mean they can't interact with your grid service. In this tutorial, find out how to create a proxy that lets clients -- even bandwidth- and processing power-limited clients -- interact with your grid service using e-mail.

Building a unified grid, Part 2: Portlet interfaces in the grid user environment
Building a unified grid, Part 1 discussed what it means to "grid-enable" an end-to-end process and described the grid-based system architecture developed in the Telescience Project at the National Center for Microscopy and Imaging Research. In this article, we tackle the grid interface. Find out why the grid interface is critical to the end-to-end process and how the use of portlets has led to a richer grid user environment for NCMIR's grid project.

Use IBM Cloudscape/Apache Derby as RFT database in GT4
This article describes the code and configuration changes required to use the Apache Derby open source database management system (DBMS) as the database manager for the Reliable File Transfer (RFT) service in Globus Toolkit 4.0 (GT4). GT4 currently supports the PostgreSQL and MySQL DBMS. As a 100-percent Java technology system, Derby can be embedded in a GT4 distribution, which would greatly simplify installation, configuration, and operation for your grid. The core GT4 component that requires a DBMS is the RFT.

WS-SecureConversation The Web Services Secure Conversation Language is built on


WS-SecureConversation
The Web Services Secure Conversation Language is built on top of the WS-Security and WS-Policy models to provide secure communication between services. WS-Security focuses on the message authentication model but not a security context, and thus is subject several forms of security attacks. This specification defines mechanisms for establishing and sharing security contexts, and deriving keys from security contexts, to enable a secure conversation.

Building the business case for grid Building a business case


Building the business case for grid
Building a business case for an investment in grid computing requires more than just showing technical merit. Project sponsors need to supply metrics to support both the business need and technology impact and demonstrate the game-changing effects of grid computing. This can require benchmarking, measurement, and justification of resources, both in financial and human capital terms. In this article we'll explore how to build the case for a grid project.
