A Networking Approach to Grid Computing - Minoli, Daniel

. .

Résumé :

• Explores practical advantages of Grid Computing and what is needed by an organization to migrate to this new computing paradigm
• This self-contained reference makes both the concepts and applications of grid computing clear and understandable to even non-technical managers
• Explains the underlying networking mechanism and answers such questions critical to the business enterprise as
  • What is grid computing?
  • How widespread is its present/potential penetration?
  • Is it ready for prime time?
  • Are there firm standards?
  • Is it secure?
  • How do we bill this new product? and
  • How can we deploy it (at a macro level)?
