Three categories for Grid

1. computational grid
2. data grid
3. service grid: instead of providing computational or data resources enables sharing of specific functions defined and exposed as services

Cloud Computing: Resources come from the cloud, a public network, rather than a specific identifiable system.

The rational behind cloud computing:

• the underlying complexity of the system and their characteristics should not only be hidden from the underlying users but for the most part to the technical users as well. Amazon Simple Storage Service (SimpleDB) is a webserivce providing storage capabilities.
• It is not only about computation and data
  

Potential Research challenges

• adaptability in response to changes in the nonfunctional requirements of the system
  
• From changes in internals of components to external changes
• Reaction on Message interceptions received by the infrastructure
• Safety and Security of the profiles

Interesting points

• nonfunctional properties management
• rapid adaptation
• dynamic composition
• distributed system integration

IBM's perspective on autonomic computing

• Self-configuration: adapts automatically to dynamically changing environments
  
• Self-healing: system discovers, diagnose, and reacts to disruptions
  
• Self-optimizing: systems monitor and tune systems automatically
• Self-protecting: systems anticipate, detect, indentify and protect themselves.
