4. Grid Computing
• A Grid Checklist:
• …coordinates resources that are not
subject to centralized control
• …using standard, open, general-purpose
protocols and interfaces
• deliver nontrivial qualities of service

(2002)
5. Grid Computing
• Back to 2002/2003
• Two REVOLUTIONS (?):
– Begin of the Multi-Core era
– Grid Computing
Feb. 2003 issue May 2002 issue
9. A Revolution?
• Revolution* (a drastic and far-reaching change
in ways of thinking and behaving) quot;the industrial
revolution was also a cultural revolutionquot;
• Evolution* (a process in which something
passes by degrees to a different stage) quot;the
development of his ideas took many yearsquot;

23. McKinsey's Cloud Computing
Report Is Partly Cloudy
“Clouds already make sense for many
small and medium-size businesses, but
technical, operational and financial
hurdles will need to be overcome before
clouds will be used extensively by large
public and private enterprises”

32. A little bit of Physics
> Commutation Relation
[Grids, Clouds] =
Grids*Clouds-Clouds*Grids ≠ 0
We can build Grids of Clouds and we can
build Clouds of Grids and the final
outcome will be different….
…So Distributed Computing exhibits a
Quantum behavior and not Classical ☺
51. Summary
• Cloud Computing is Here
• Tremendous Economic Impact
• Small Companies / Startups already
using it
• Large Companies must assess this
new technology
• Will be deployed Everywhere soon
