The second part of a new series of tutorials on building a grid application based on standardized web services like WSRM (Reliable Messaging) and WS-Security is now available.

This second part looks at the development of a security model using the WS-Security standard. In this tutorial we introduce the basics of WS-Security, how to create and share a token and how to use the token to verify transactions between the grid manager and individual grid nodes.

Once again, the tutorial has made top picks on the IBM developerWorks Grid computing page!

As mentioned for Part 1, this is a joint venture between myself and Tyler Anderson. Tyler has provided the code, based on my design guidelines and thoughts for the grid. Tyler has done a stunning job on the code - it gets even better as we start to approach some of the more interesting stuff like WSRM and resource properties. The final grid solution - which I’m just writing up now, is fantastic.

Unfortunately, you’ll need to wait a few more weeks before you get to see the final code!
