A dream called … the Grid

3

• Grid computing is a concept which takes distributing

computing a step forward

• The name ‘Grid’ is chosen by analogy with the electric

power grid:

─ Transparent plug-in to obtain computing power

without worrying where it comes from

─ Permanent and available everywhere

• Grids are computing infrastructures providing seamless

access to computing power and data storage all over the

globe

Our world … and one step further!
