"A previous article introduced you to the Grid computing concepts, the new open standard software architecture model (Open Grid Services Architecture, or OGSA) and the new programming model for Grid computing (Open Grid Services Infrastructure, or OGSI). The Globus Toolkit version 3 is the major reference implementation of the OGSI standard (see Resources). This software is used by a number of technology initiatives including utility-based computing, on demand computing, virtualized resource sharing, distributed job schedulers, and similar applications as a proof of concept for open standard interoperability using OGSI and Web services architecture. One such recent initiative is the IBM alphaWorks Emerging Technology toolkit (ETTK) with Globus GT3 software and samples. This software and surrounding architectures are still evolving, and this article concentrates on the recent and stable software preview (Globus GT3 alpha 3) from Globus.

"This article presents three sections on the Globus software architecture and the programming model through sample code:

  1. "The high-level architecture of this toolkit
  2. "The programming model and tools
  3. "A simple 'Stock Quote' Grid service creation using a top-down design approach starting with Web Services Description Language (WSDL)..."
