Part 4 of the series Tyler and I have been writing showing you how to build a Grid using Web Services has appeared on IBM’s developerWorks site. Here’s the precis:
The effective exchange of information is vital in any grid. In a resource-led grid like the Movie application covered in this tutorial, you must have effective exchange of the data being stored between nodes in the grid, otherwise information storage is pointless. In this, the fourth of a six-part “Building a grid using Web services standards” tutorial series, you’ll learn where to exchange data in the application data, how you can ensure the exchange of information, and how to combine standards like Web Services Reliable Messaging (WSRM) and Web Services Security (WSS) to provide reliable and secure exchange of information.
A more detailed description:
In this series, we’ll look at the ground-up development of a grid-based movie application, using the different standards to implement the different components of the system — which together provide the entire structure of the grid application. The application in question is a combination of resource and CPU grid technology for the distributed storage and recovery of movie files in a database. By using grid technology, you can spread the load of the storage requirements and provide additional functionality throughout the grid for manipulating and accessing movie files in alternative formats, sizes, resolutions, and configurations.In this tutorial, you’re going to produce an environment for the grid nodes to store and return resource properties and information through Web services. You’ll also build a client that obtains the information for each of the nodes on the grid manager, which, in turn, sums up the information and provides it to grid client.
