Tony Scott, chief technology officer for General Motors, steps on the brakes a bit when it comes to grid, as captured in this Q&A just published in ComputerWorld:
- Large vendors haven't yet mapped core legacy applications to the grid environment.
- There aren't yet reliable management interfaces for the grid environment.
- Dynamic distributed computing structures that are grid-enabled will amplify the importance of frontier security issues, such as identity management and usage policies.
It may depend on where and how your grid is deployed, of course. Many industry experts say most grid deployments are likely to remain within firewalls, which may lessen security requirements. Last fall, I had the opportunity to speak with Don Deutsch, president of the Enterprise Grid Alliance, about the more internal route grid will take. The Q&A is posted at Database Trends & Applications.
