Chapter 1 Oracle 10g Grid Computing
These two important resources; processing power
and storage systems, are the main areas of attention for grid
planners and grid users.
What is Grid?
Back in 1998, Carl Kesselman and Ian Foster in
the book “The Grid: Blueprint for a New Computing Infrastructure”,
while attempting to give a broader vision of Grid [1.2], wrote:
computational grid is a hardware and software infrastructure that
provides dependable, consistent, pervasive, and inexpensive access
to high-end computational capabilities.” [1.2]
Subsequently, Ian Foster with Steve Tuecke,
redefined the definition stating that Grid Computing is concerned
with ‘coordinated source sharing and problem solving in dynamic,
multi-institutional virtual organizations’. They further noted:
“The sharing that we are concerned with is
not primarily file exchange but rather direct access to computers,
software, data, and other resources, as is required by a range of
collaborative problem solving and resource-brokering strategies
emerging in industry, science, and engineering. This sharing is,
necessarily, highly controlled, with resource providers and
consumers defining clearly and carefully just what is shared, who is
allowed to share, and the conditions under which sharing occurs. A
set of individuals and/or institutions defined by such sharing rules
form what we call a virtual organization.”
