Autonomic/self healing computing

Improved MIS

Market place computing


Important Lessons for EveryoneFitting in !• Adding GRID into an existing infrastructure is painful !

• Ignore the people and emotional impacts of GRID at your peril !

Governance• Operational aspects are as important as the architecture

• Leverage expertise externally and internally to ensure delivery

Don’t let the operational consume you !• Providing the resource generates the demand exponentially

• Running a GRID takes you away from evolving. Innovating while operating is crucial


The Technology comes of Age

The technology is at the level to support our demanding environment

Impacts to long-term operational costs are compelling and realizable

Business can support the initial investment
